Unless your disc is a weird fake, it sounds like an issue with your player. Is there no "audio" button on your Blu-Ray player remote to switch tracks? How do you normally do it?
Yeah it crossed my mind it could be fake though it really doesn’t look like it. But then again I have no real way to tell. I mean the disc at least is Dolby Vision.

I have an x800m2 and a UBK90. I tried it on both with no way to change the audio on either. They both have audio buttons which change the audio just fine on other movies.

I did discover that if I try to play the disc with Dolby Vision turned OFF the disc defaults to an alternate audio track saying the disc is meant to be played in Dolby Vision.

Sorry for late reply. I encoded it to HDR quality and uploaded to youtube for quick check. And you can find download link under video if u want to test on your tv.

This is still old 1080p upscaled to 4k. I can see some one already uploaded bluray in torrents. I will try to upscale original 4k video to 8k and upload to youtube. So youtube not going compress it so hard and you can watch in good quality on youtube if you choose 4k res(YouTube not compressing videos so hard if you uploading in higher res). And again sorry for late reply i had lost my ssd so i needed to render new video.

//Edited
I checked new video. Its seems its little bit different from old version. It have few changes. But coolest part of the black screen is left!

Yeah that won't work, mkv doesn't support Dolby Vision

Richard, I am downloading that torrent now, if I burn it to a blu ray & attempt to play it in my UB820 it should play in Dolby Vision on my A1E correct?

Assuming you have a UHD-BD burner, then...maybe?

I do have a UHD-BD burner but only have BD-R DL discs that are 50GB in size but this ISO is only 24GB



So the only thing stopping this working is that fact that I dont have a BD-XL disc if that is a requirement for the player to play Dolby Vision content.

In theory, yeah, because HDR10 etc isn't in the Blu-Ray spec so wouldn't work on a regular BD-R disc

I guess there is only one way to find out & that's to burn it & see. Just a waste of a disk if it does not.

So not a total fail, the disk plays but only in HDR10 not in Dolby Vision & displays a message on screen.



I have the Dolby Vision setting enabled on the Panny so I can only think that my AVR cant pass Dolby Vision?


Going to try connecting the player directly to the TV & see what happens.




EDIT: Looks like my hunch was right after connecting the player direct to the TV everything plays in Dolby Vision as intended.


So Dolby Vision does not required BD-XL discs either.

Fairly certain your AVR does pass Dolby Vision, that's strange...

Thank you for this. I don't have a Blu-Ray burner so I just put the folder onto a USB drive. Both my LG-UBK90 and my LG-B7 played the MTS files in the stream folder fine. Receiver showed I was playing Atmos from both sources. My favorite clip from the Dolby Access app (no longer there), Core Universe, sounded just as good and looked as good as I remember. Despite the sound working well, my TV showed HDR. None of them came up as Dolby Vision. I own Kong: Skull Island, Wonder Woman, and Valerian in 4K. The clips did not sound as good as my 4K discs. The bass seemed to be turned down and the surrounds/heights turned up. Also in Wonder Woman when she is running I noticed some compression blocking and other effects not seen on my 4K disk. Still worth every minute of time I spent with it. Thank You.

TV: LG OLED 65B7A, Receiver: Marantz SR-6012, Blu-Ray Player: LG UBK90, Fronts: JBL S312, Center: JBL S-Center, Surrounds: JBL S38, Top: JBL S36 (4), Subwoofer: 2 PSA S3000i and one PSA XS-30se--- 5.3.4 setup

So after messing with a few settings on the Vertex you are correct my AVR can pass DV no problem.

I may have spoken too soon on the demo disc though, some clips play fine but others after 15 seconds the audio starts to break up & then disappears completely. The video is still present but is choppy sometimes.

The Kong Island & Wonder Woman clips are ones that are effected among others, Core Universe plays all the way through no problem but the audio volume is very low, I have to turn up my master volume well above normal levels.

I thought this was my setup so I plugged my BD player directly into my TV & it does exactly the same so I can only come to the conclusion that this is a problem with the content on the disc itself?

I burned at x2 & verified the disk successfully so I dont know what else I can do to check.

Anyone else burned the torrent to a disk & tried it?

Yeah, that's normal, it's just recorded low, like 10dB lower than "normal"

I presume all the clips play for you in DV & Atmos no problem?


Really got me scratching my head, tried various different cables that pass 4K, 60Hz, 4:4:4 10bit no problem.



It does see like some sort of signal issue as its like its handshaking constantly as the clip plays like the signal is being lost & found.


I mean I even tried a 70cm cable which from my knowledge at that length most cables should have no issue passing any content.

I have this disc and the demos are Dolby Vison / HDR / TrueHD+Atmos / E-AC3+Atmos / AC3.
Dolby Vision is dual layer when found on disc.
The first video stream is 4k and contains the HDR, the second video stream is 1080p and contains the Dolby Vision information to add to the first 4k HDR stream.
Your disc player acts as the "composer".
The USB jack on the LG OLED will play Dolby Vision files (LG demos in the .lge file container) that are single layered (all info is in one stream).
With a UHD disc player you can output Dolby Vision to your compatible TV via HDMI and output TrueHD+Atmos to your Atmos compatible audio receiver.
If you take the m2ts files off the disc and put them on USB you will only get HDR because it's Dolby Vision in dual layer.
Also, you can get Atmos from your TV ARC from the E-AC3 stream if your TV supports it, the latest LG C9 TVs have eARC so they can pass TrueHD+Atmos over ARC.
I have a LG C8 with a Samsung HW-N950 and these are my playing options:
Good: m2ts file on USB plugged into TV > HDMI to soundbar (this gets HDR and E-AC3+Atmos)
Better: m2ts file on Vero 4K+ > HDMI to soundbar > HDMI to TV (this gets HDR and TrueHD+Atmos)
Best: UHD disc in UHD player > HDMI to soundbar > HDMI to TV (this gets Dolby Vision and TrueHD Atmos)

Dolby Vision is better than HDR and TrueHD+Atmos is better than E-AC3+Atmos, but the difference is not drastic.
If you can get HDR with E-AC3+Atmos, you should be pretty content.

*You could mux the dual layer m2ts into a single layer MP4 to get Dolby Vision via USB but the best audio you can get going that route is AC3 5.1.
The only way I know of to get Dolby Vision with TrueHD+Atmos is from a UHD disc player or files through OPPO UDP-203.
LGE demo files will not have TrueHD+Atmos and even if they did you'd need eARC for that anyway.

Maybe one day someone will figure out how to make proper Dolby Vison with TrueHD+Atmos MKV files, but even then, it would require a player with a license from Dolby to act as the DV "conductor".

You have the March 2018 UHD Disc? And it plays back the files In Dolby Vision with TrueHD Atmos? Wow. Weird. I have the disc and it just would not play anything other then DD+ Atmos. The Dolby Vision was fine though.

I am still having issues with the March 2018 disk with some clips losing sound shortly after starting. I have tried five different cables now between player & TV.



I even purchased a certified HDMI cable but still no difference.


I just cant work out whats causing it, the TV, Player or the disc.

I wonder if it's a Cinavia problem...

I dont get a message, it's like there is a bottleneck somewhere.


On the Sony when a handshake occurs with a source the info/status bar appears at the top of the screen.



The same happens when the audio starts to break up & the video becomes choppy the info bar appears at the top the screen like a handshake is happening.

The following is the media info for the stream belonging to "Core Universe" aka "See. Hear. Spectacular.".
Look at the first audio stream, it is Dolby TrueHD + Atmos, second audio stream is E-AC3 + Atmos, and third audio stream is just AC3.
Every demo on the disc has the same specs:
Video 1 = 4K UHD HDR
Video 2 = Dolby Vision
Audio 1 = Dolby TrueHD 7.1 + Atmos
Audio 2 = E-AC3 5.1 + Atmos
Audio 3 = AC3 5.1

I'm not sure why you are getting lossy Atmos from your disc.
What player and receiver do you have?

I have a Sony X800m2. It plays other Dolby Vision discs with lossless audio just fine. Only had the trouble with the 2018 March UHD Demo disc. Maybe I simply had a defective disc.

Question Unidentified Demo Disc

Sorry to bump this, but does anyone know if the demo that is shown at 0:51 in this video is available anywhere?

That looks like the screen that pops up on the Dolby Demos on my TCL 6 Series. From it's Dolby app. It has a bunch of Dolby Vision and Dolby Atmos demos in the app. My XB1S and XB1X also have some of the same Dolby demos in the Xbox Dolby app.

Thanks. I found a bunch of demos with the same splash screen. Thanks for the help. Have a great day.

It would be interesting to know how they did to "strap-up" from the m2ts file of Blu ray UHD, a mp4 content that has both dolby atmos and dolby vision ...

It's only E-AC3 (Dolby Digital+) Atmos in the mp4 container, not TrueHD Atmos

I meant atmos losses + dolby vision ... do you know how you can succeed by having the m2ts file that contains double video track?
