  Info and Tips for AVR, Subwoofer, TV or Disc Player Problems
  
• Cleaning Movie Discs that Freeze or Skip with Isopropyl Alcohol
  This has fixed problems I've had with some UHD Discs that froze during playback.
• Panasonic owner reports of Movie Disc Startup Problems with BD-Live Enabled.
• 31 Audio Articles from Audio Engineer Tom Nousaine (PDF Downloads)
  (web archive link added to my original June 2014 post about his passing away.)
• Problems after an update? Or suddenly seeing strange errors?
  If you have "Quick Start" enabled, try disabling it, & power off/restart.
  If that doesn't help, power off, disconnect power and then press device's ON button.
  ( I never use quick start on TVs or players. I've seen it cause problems for others at times.
  My guess is that sometimes cached data for quick start gets corrupted or is out of date.)
• Device Turning ON or OFF by Itself?
  - Turn OFF the device's HDMI Control/CEC, called VIERA Link on Panasonic, on Sony Bravia Sync (some Sony players have it under under HDMI Control), and Simplink on LG. (On the LG 4K/Blu-ray players I've had, there is no setting to turn off HDMI-CEC control. Some have used an HDMI adapter that has the CEC pin disconnected.)

  If the dent isn't at the edges, I use a metal spoon on the inside surface with the steelbook placed on a hard flat surface. (I place a paper towel on top of a wood stool, and I press down while rubbing the rounded spoon surface over inside area of the dent.)

  - Set TV's Black Level setting to HIGH (low is normally correct).
  - For LG TVs, the Black Level setting is in the (Picture Mode) Picture Options.
  (Black level high is a workaround for the original season 8 incorrect black level.

I used a flashlight to check the disc for any scratches/smears, etc and none were evident. Despite the disc appearing pristine, the first attempt to play in my Sony X800 froze (black screen) at the start of the 22 second Universal intro. Did the usual unplug/restart and it got a bit farther, but froze at the 6 second mark of the 22 second spinning Universal logo intro. I suspect many owners would have returned the disc to the store for an exchange, but as I've mentioned before with other problem discs that appeared pristine, I rinsed off the play side with isopropyl alcohol. It then it played fine for the entire 3 hour movie. (It's a BD100 disc.)

About Dec. 1, 2020 Version 6.4960

• Improves general performance of the TV

"Affected models: RX-V4A, RX-V6A, RX-A2A, TSR-400 and TSR-700, for certain pass-through compatibility with Xbox Series X, NVIDIA RTX30.

From the time we launched several AV receivers in 2020, we stated that we would support emerging HDMI 2.1 capabilities  including pass-through of 4K/120Hz or 8K/60B  in these models via future updates. A hardware update is required on the above AV receivers only for customers who plan to connect Xbox Series X or NVIDIA RTX30 at 4K/120Hz or 8K/60B to these select AV receivers..."

"A bug in the latest HDMI 2.1 chipsets sourced by Panasonic and utilized in the new Denon, Marantz and Yamaha HDMI 2.1 AV receivers. This bug can inhibit pass through of 4k/120Hz HDR and 8k/60 HDR for some devices like NVIDIA's newest graphics cards and the latest XBOX Series X gaming console. When engaging these resolutions with these source devices directly connected to an HDMI 2.1 capable receiver utilizing the Panasonic HDMI 2.1 chipset, the user can experience a blank screen."

"Sound United completed additional testing and is pleased to report that 4K/120Hz passthrough works without issue on Nvidia and PS5 devices. Outside of what was originally reported regarding Xbox at 4K/120Hz output setting, we have had no further HDMI 2.1 device interoperability issues reported as of this writing..."

My Experience with the Panasonic DP-UB420
- My notes and tips on the UB420, including tests with 100GB discs.

Panasonic Trick to Play (Some) Region B Blu-rays (YMMV)
- Details. (Firmware 1.69 didn't break it.) Tip doesn't work with all discs,
so I have a Region B Sony S6700, which also plays Region 2 DVDs.

   It was great to be able to watch region B locked 3D discs of Terminator 2 and Ratatouille on my LG OLED (3D/4K) TV. (Unlike some other discs like Valerian 3D, the "Stop, then Top Menu" trick I often used with my Panasonic UB-420 and DMP-BDT500 did not work with the region B Terminator 2 3D & Ratatouille 3D blu-rays.) Region 2 DVDs (PAL) also played fine. (Tested with Region 2 Peaky Blinders series 1+2 DVD box set bought at a Goodwill for $2.)

   Exchange rates vary, but at the time the player (new) cost appx $105 (US) after VAT removal, plus shipping. (Best price I'd seen on an all-region S6700 was just under $200.) I already have several region A players, and a 4K/UHD player. (All standard 4K/UHD movie discs are region free. And of course some blu-ray movies are all region also, but not all.)

    The Sony BDP-S6700 has 802.11 a/b/g/n WiFi with 2.4/5GHz support, Bluetooth v4.1, Ethernet (100BASE-T) and a USB 2.0 port. I like the Sony's options/features and 3D support, but use it only for disc playback, not streaming/apps or bluetooth. (And I'm not using any network connections.) As I've mentioned with other Sony players, I set the output mode to "Direct" (via Options menu during playback) - the setting is persistent. (I've not noticed any DNR with that setting personally.) This UK BDP-S6700 shipped with firmware M32.R.0486, which isn't the latest (.0527 from 3/12/2019 is, as of this post date), but I don't plan on updating unless I have to.

• Improves image quality in specific scenes.

• Removes the Gracenote® function.

(change from previous M21.R.0180)
• Removes the Gracenote® function

I've not been able to test if this possibly fixes the hard freezes from Dolby Atmos Intro/demos noted with previous firmware versions. (An issue for years, never fixed.)

Compared to previous Official release UDP20X-60-0625, the major changes are:
1. Added the "HDMI IN BYPASS" mode for Dolby Vision passthrough via HDMI In.
2. General fixes and disc compatibility improvements based on recent and upcoming UHD Blu-ray releases as well as user-submitted samples.

FYI: Reportedly even in Bypass mode the Oppo HDMI Input can't pass Dolby MAT (Metadata-Enhanced Audio Transmission) PCM Atmos that Apple TV uses. (It can pass bitstreamed Dolby Atmos and bitstreamed DD+ Atmos.) If your Apple TV has Atmos enabled, you won't get any audio using the Oppo's HDMI Input even when set to Bypass.

(If you missed it earlier, there's info on Oppo's HDR to SDR modes below.)

Fix for Pink/Red/Purple Tinted Screen with Dolby Vision on Oppo 203/205
If you see pink or red/purple tinted video during Dolby Vision playback after the above firmware update, try changing the Oppo's Dolby Vision setting to "TV Led" processing instead of "Auto". (Early Sony DV TVs used "Player-Led" Processing, later models use TV Led.) Several owners (typically LG TVs) have reported problems with Dolby Vision (Pink/Red tinted video) after the UDP20X-65-0131 update with Oppo's Dolby Vision set to "Auto", typically if the Oppo HDMI video was connected to a Receiver. ("Auto" may be OK if player directly connected to the TV.) The fix is to set the Oppo's Dolby Vision to "TV-led processing" unless your Dolby Vision compatible TV is an early Sony DV model, which used "Player-Led" Dolby Vision processing. (The "Auto" setting worked fine with previous firmware versions they said.)
Note: Later LG Dolby Vision TV Models may not show the pink/red tinted screens if Oppo set to "Auto", but should still be set to "TV Led" processing. Some say the "Auto" setting actually used Player Led and that also caused a problem with playback of some Dolby Vision UHD Movies, like the Daniel Craig Bond Movies. (And also causing banding in some cases.)

"Resolves an issue that may prevent iTunes from playing media to third-party AirPlay speakers. It also includes minor app and performance improvements."

Compared to previous UDP20X-60-0625, the major changes are:
1. Added the HDR10+ support. A HDR10+ enabled TV is required to view content in HDR10+.
2. Added the "HDMI IN BYPASS" mode for Dolby Vision passthrough via HDMI In.
3. General fixes and disc compatibility improvements based on recent and upcoming UHD Blu-ray releases as well as user-submitted samples.

Also some Apple TV 4K users said the new Bypass mode still didn't work for Dolby Vision in their setups. Black screen on TV after Dolby Vision icon appeared. Some tried both a single HDMI cable (Audio and Video) through an AVR that supports Dolby Vision, and the dual HDMI cable method - HDMI video only connection to TV, HDMI audio only connection to AVR. (I'm assuming they're using HDMI 2.0 certified cables and that they tested Apple TV Dolby Vision function with a direct HDMI connection to the TV to verify that works.)

Update: I saw posts from 2 Apple TV users that wrote Oppo Support about the Dolby Vision problem (noted above), that said they were sent a download link for a revised Beta Firmware (same version number) that solved the problem. (It did not solve the Dolby MAT Atmos issue however.)

• Improves HDMI connection stability.

"Picked up a Sony UBD-X800 locally and so far impressed at the value (for $149.99). Feels like a much higher quality build than the LG UP970 player I was also looking at. If LG hadn't pulled the Dolby Vision update I may have tried the LG (at $199.99 sale price), but seeing a lot of complaints on drive noise with some UHD discs (not all) and no word when the DV update would be re-released, I decided on the Sony. (Update - On Feb. 8th, 2018 LG released UP970 DV firmware update.) Was also considering the Philips BDP7502 since it's supposed to get a DV update eventually, but not able to find one locally and heard of some 3D playback issues but that might just be a firmware issue. (Update - On Feb 28th, 2018, Philips released BDP7502/7302 DV firmware update.)
   The Sony X800 is fast to load discs, but not quite as fast as the Oppo 203 (which has Dolby Vision, but no apps) but for $150 locally (easy return if necessary) - well worth it. I had to update the X800 firmware via USB (link), as it had problems contacting the 'provisioning server' with my Ethernet connection. (The firmware update solved the problem with the network update check in the player.)
   My Sony X800 player settings for improving disc playback reliability (IME).
(Remember to Update Player Firmware first and if you have a disc problem (freezing, skipping, etc), even if it looks OK, Clean it with Dawn liquid soap, or Isopropyl Alcohol.)

Sony X800 Player Settings Tips (also useful for other Sony models.)
Options not listed below are left at defaults or Auto.

• (Audio Settings) BD Audio Mix - OFF
  (BD Audio Mix MUST BE OFF for bitstream and Dolby Atmos/DTS-X.
  But remember that disc players don't report Atmos/DTS-X info.)
• (Audio Settings) Digital Audio Output - "Auto"
• (Audio Settings) DSEE HX - OFF
• (Audio Settings) Audio DRC - OFF
• (Audio Settings) DTS Neo:6 - MUSIC *
  (* I prefer Neo:6 surround for Stereo Music CDs, a personal choice)
  
  
• (System Settings) HDMI Settings-> Control for HDMI - OFF
• (System Settings) HDMI Audio Output - "Auto"
  (* Auto detects the player's HDMI audio connection at either HDMI 1 or 2.
  If you're always using a specific HDMI 1 or 2 setup, you can select that instead.)
• (System Settings) Quick Start Mode - OFF
• (System Settings) Auto Display - OFF
• (System Settings) Software Update Notification - OFF (I check manually)
  
  
• (BD/DVD Viewing Settings) BD Internet Connection - "Do Not Allow"
  
  
• (Screen Settings) Screen Format - NORMAL
• (Screen Settings) Cinema Conversion Mode - AUTO
  (some have recommended Video mode, but I use Auto.)
• (Screen Settings) DVD Aspect Ratio - LETTER BOX
• (Screen Settings) 24p Output
  - Ultra HD Blu-Ray/BD-ROM - AUTO
  (There are rare 60P 4k discs like "Billy Lynn's Long Halftime Walk" & "Gemini Man".)
  - DVD-ROM - OFF
  (I use only Discs, so left the Data & Network content off.)
• (Screen Settings) 4K Upscale Setting - OFF
  (Some options are for Sony TVs/Bravia Mode. I use an LG OLED TV.)
  
  
• (Network Settings) Auto Home Network Access Permission - OFF
• (Network Settings) Remote Start - OFF
  
  
• (Bluetooth Settings) Bluetooth Mode - OFF
  (Off since I don't use the Bluetooth audio feature.)

The X800M2 and X700 models also have a Dolby Vision (On/Off) setting.
(These came out after the original X800 I bought in 2017.)

I don't use a Sony TV, so I can't comment on using the player's "Bravia Mode".
(See page 21 "Screen Settings" in the X800M2 PDF user manual.)

Options During Playback (NOT available in Dolby Vision):
During Disc playback, I set "Options" (button on remote) Video Settings to "Direct".
(Some pre-UHD Sony player owners say any other setting applies some DNR.)

BTW: Personally I don't use any streaming/apps or USB file playback.

   The X800 feels very solid (8+ lbs) and seems very quiet so far. It also supports Bluetooth Audio and plays SA-CD, DVD-Audio and 3D Blu-ray discs. (Also has Netflix 4K HDR and Youtube 4K HDR support - Amazon 4K but not HDR.) I've had good luck with Sony players in the past (other than an S7200 that STILL doesn't have a firmware update to fix Atmos intro lockup (requiring unplugging the player) with the early seasons of Game of Thrones). (Update - Sony posted a new S7200 firmware on 6/26/2018, but problem still there.) I will let you know if I see any X800 problems with discs.
-Doc
(Notes below were BEFORE Oct. 2018, March 2019, Aug 2021 & May 2022 firmware updates was released.)

Update: No issues playing 100GB discs of Westworld S1 4K, Mad Max Fury Road 4K, Pacific Rim 4k, Interstellar 4K, - no freezes/stutters on layer change of those 100GB discs. Also played Blade Runner 4K, Dunkirk 4K, Batman Begins 4K, The Dark Knight Rises 4K and Batman Begins 4K discs OK. Often used for back to back blu-ray movies.
Update 2 Saw hangs (player still responds to remote - but movie froze) at appx 1hr 42min into The Dark Knight 4K and at 1hr 58min of Blade Runner 2049 4K (same freeze time seen with an Oppo 203 and LG UP870 before later firmware updates.) - both times stopped playback, ejected disc and wiped it off (some tiny dust particles) and (automatic) resumed playback OK. Both times reversing to before the previous time to see if it was repeatable. I need to start cleaning all 4K discs before playing to see if that really is a factor. (It has helped for some, but not all cases but it is the first thing to try. Some think a residue from disc mfg is to blame.) Some owners (of various brands) have had repeat 4K disc problems (esp. 100GB discs), in some cases even after disc replacements. (Cleaning the BR 2049 disc didn't help with the 1:58:21 freeze with the LG 870 (before the 2020 firmware update), but the Oppo 203 played it OK after a firmware update.)"
(FYI: Oppo's 56-0224 firmware Update listed a fix for Blade Runner 2049, but not sure it solves the problem above for everyone.)
(Test with March 2019, X800 M36.R.0338 Firmware - Tried Blade Runner 2049 4K disk again (cleaned), and skipping to the chapter at 1hr 52 Min, it played through fine (no hang/freeze/stutter at 1:58:21), although I'd rather verify it was ok with a full playback from the start, as I wonder if heat (or buffering) - not just a layer change - is a factor. I say that as often you see owners say that after a freeze at a certain point, rewinding to just before that point and playing again worked.)

Any Audio dropouts playing Dunkirk?
(I saw 2 X800 owners report audio dropouts during loud effects (like explosions) in Dunkirk. Since some graphs show the movie's audio has clipping, my first thought was to check the player's Audio DRC (Dynamic Range Control) setting, but someone later said turning off BD Audio Mix solved the dropouts. Audio Mix off is typically step 1 in player setup for receiver users so the player bitstreams audio to the Receiver for decoding DTS/Dolby/Atmos, instead of the player sending PCM audio. It's on by default, typically used for button sounds and things like optional commentary during playback.
Turning BD AUDIO MIX OFF has solved many X800 Audio problems.
It should have been off by default IMO. See my Sony 4K Player Settings Tips.)

I didn't notice any audio dropouts with Dunkirk (4K UHD or Blu-ray), and yes, Audio DRC has been off since day 1. (Also BD Mix off, as I noted in settings above.) Wish Nolan would have 'allowed' Atmos or DTS:X on his discs, but I guess clipped 5.1 was "director's intent" again, lol.
(Ironically, I noticed some Nolan 4K disc Intros (like WB Logo) had Atmos audio.)

Any issues with using HDMI 2 (audio only) port?
(An older Integra Pre-Amp user said he's tried 2 X800s but can't get Audio playback from HDMI 2. (I assume using a known good HDMI cable - verify that first.) Tried System Settings > HDMI Audio Output set to HDMI2 and "Auto". ("Auto" is nice if sometimes you want to leave the AVR off and just use the TV speakers. Otherwise "Auto" should detect an AVR (on) connection with HDMI2 and use it instead.) I'd also set System Settings > HDMI control OFF (all devices, unless you need ARC). Of course AVR's input set to the port that X800's HDMI2 is connected to. Power up TV first, then AVR (verify input set correctly), then player.)
Update - Another older model Integra (DTR-9.3) user reported same issue when Integra has HDMI connection to the Projector. (Disconnecting cable from Integra to Projector solves it - or use an HDMI switch on that connection. Same issue seen with some other older receivers when used for audio only connection from player and player video connection to a display.) Possible HDMI Control issue - awaiting reply to see if disabling HDMI Control (CEC) helps.

No problems with using the X800's HDMI 2 (Audio only port) connected to my Yamaha RX-A3050, with HDMI 1 going to the TV HDMI port (set to UHD of course). The X800 player has HDMI Audio Output set to "Auto", and verified HDMI control is off (on everything). I originally was using a single cable setup, but later switched to separate Audio to AVR and Video to TV. HDMI audio "Auto" setting works fine for me.
Hope you have a Merry Christmas. Stop by over the holidays and I'll demo all the Nolan 4K disks - Dark Knight Trilogy, Interstellar, Prestige, Dunkirk, Inception. Long story on them (some raised black levels), but no regrets except for busted cases and scratched/stacked discs."

BackFlashing Yamaha Aventage AVR Firmware (YMMV)
• Disconnect AC Power from Receiver (suggest using Switched Outlet strip)
• Insert a USB Flash drive with previous Firmware (FAT format with firmware file only)
• While holding down "Pure Direct" Button, Switch AC power On

• I tested several of the worst (clouding) examples (and discs I liked most - Blade Runner disc 1, Matrix 1, FMJ) in the Toshiba A20 and they played all the way through. (I'd forgotten how good they looked.) I separated out all discs that showed any clouding at all and will test them as time allows. (This was before using the plastic polish.)
  
  
• It may not be related, but I also noticed that -all- of the HD-DVD cases that had glossy interiors had a layer of some sort of film/fogging on them. (As if the plastic had outgassed over time, or was it just related to mfg plastic mold release? 4K UHD disc cases often have a LOT of oily film, which I think is the mfr's release coating for the injection mold. In some cases you can see the round suction cup spots, which shows this oily film was already present when it was produced, and not something that outgassed over time. Several times I have had to use alcohol to remove it from the discs to fix playback issues.) A couple cases had a matte/pebble-like finish inside (i.e. HD-DVD Unforgiven) and were still pristine. The heavily clouded discs were all from the cases with glossy interiors.
  
  
• Some think the problem with HD-DVD disc 'rot' was from a specific batch or mfr. (Google 'hd-dvd rot cinram' and you'll see some hits, including one on LaserDisc rot.) I wasn't able to tell if any of mine were made by cinram but did notice two different disc types: all silver on the back and others with a white center ring. (The worst clouding examples were the white ring disc type.)
  
  
• (Cloudy) HD-DVD Disc Cleaning: One tip I saw for cleaning the discs to remove the milky clouding was using plastic polish. I remembered years ago (2005 or so) I'd bought some "Meguiar's Scratch-X" (fine scratch and swirl remover) to polish haze out of an old mustang's plastic speedometer lens. (Never tried the later Scratch-X "2.0".)
     I used a small amount of it on the discs (worst examples first), just lightly rubbing it with a finger around the back of the disc. Waited a few seconds and buffed it off with just toilet paper. Bingo - all the clouding was gone. (I was impressed at how well the Scratch-X worked for this, but I have not tried it for scratches on discs, and only would if any were bad enough to affect playback. I'm not trying this on Blu-ray discs.)
