Can you please recheck Shield TV on MIF bath fight scene with capture card?

Is it me or there is some noticable improvement with 8.2.2 update?
Can't spot red blocking while playing mkv via plex.
DV triggered

Maybe I just missed this very frame.

Meanwhile Dr Sleep still has noticable red push
Waiting for @Manixx2020beyound but as far I can tell, it's not fixed nor improved: https://screenshotcomparison.com/comparison/10385

As for MI, I didn't compare it with my x700 but I still can see the red spot.
It can be hard to see in motion, but if you pause at a couple of places, you can see it.

To throw in a little detail to the mix. CX can play Dual Track DV MP4 files, but the file has to have been made using mp4muxer v1.0.0. The latest version of mp4muxer, v1.0.1, does something with file that it isn't played by the tv anymore. I checked the code changes, and it may be the change where they introduce the Alternate Group flag. With v1.0.1 this is set to 1 for both the BL and the EL+RPU tracks, previously this was 0. The BL track is also set as the "default". It may be that this is either wrong for DV files from a MP4 spec point of view, or, the TV has a bug requiring the group to be 0. It is still required to be MEL.
The issue with the mp4muxer version also exists, btw, with the previous generation of LG oleds. You either have to use v1.0.0 or make changes yourself to v1.0.1. No restrictions on MEL or FEL, however. Really does seem like LG might’ve taken out the second decoder.

Could someone point me to the tools I need to make a BL+RPU (not BL+EL+RPU) from a FEL UHD file? I think I need the resultant file in profile 8.1. Thanks!

So an oled CX owner on avsforum just confirmed with me that the tv's internal media player couldn't play this DV DL test file properly: https://drive.google.com/file/d/1NK71Ck ... XLXEa/view

On my C9 it looked fine and played fine. Seems like LG did remove the ability to play dual layer dolby vision file from the CX (and probably upcoming oled tvs as well). That sucks.
what a mess. i'm happy i've bought an m9201.

Is there a way to know which one is what version?

If you use MediaInfo you can see what is called "Alternate Group", I think it was, set to 1 for both the BL and EL+RPU tracks for a file created with mp4muxer v1.0.1. The BL track is also set to "Default: yes".

This information is as I remember not visible with MediaInfo for a file created using mp4muxer v1.0.0.

Is the x700 able to play dolby vision m2ts file directly? Thinking of investing in a bluray player instead of relying on the oled's internal player.

Yes
Really? Since the x700 is relatively cheap, maybe people should just buy it and play the dolby vision m2ts files from it instead of going through troubles to create working dolby vision mp4 files?

that's what a lot of us here have been doing for months :)
The file needs to be remuxed with tsmuxer to M2TS or TS though. Still easier and faster than the mp4 method.

Ah yeah I saw your signature :D

What is you audio setup? Dolby atmos? Is the x700 able to output dolby atmos to the receiver while playing m2ts dolby vision files?

yep, the x700 can output any lossless audio format + Dolby Vision FEL. Subtitles also work. Cinavia free as well

Is it known why tsMuxer has to be used to remux the m2ts file from the disc again to m2ts? Is the m2ts files on the discs wrong in some way?
Is it still required to manually change the output mode to DV or has that been changed in any recent update?

The DV flags are somewhere else for a uhd-bd structure (not in the m2ts file itself).
