Hi,

What media player do Shield TV users are using to play single DV? Kodi? Other? Thanks
Plex and mx player I think are the only ones working with DV

+1
I'm trying to be optimistic, at least mediainfo is looking good :) Looking forward to some comparison shots and people with HDfury checking
Yes this new method looks promising. unlike dvdfab SL, the BL + EL + RPU are present & same size as the original, so everything seems right. I just hope the shield will actually make use of the EL.

HDfury wont tell us anything special because DV(fake or not) is always sent in an 8bit RGB container on my setup (denon avr ---> C8).

But I can do some screenshot comparison if i get a chance tonight.
Thank you, if you can try the profiles 4 and 7 like yusesope said

I have followed the steps and now have the final .mp4 file created by mp4muxer as yusesope reccomends. Can I now using it to create the .ts file in tsmuxer so that I can add the atmos track? Or I will loose some dv quality?

TSMuxer will lose some of the DV, read back a few posts. If you do that you will lose the EL bits and pieces

A quick question, if this works will it be identical (in theory) to the original dual layer source? As it has BL+El, or do we lose something like 12bit?

Its the same size so I think everything is preserved. The decoding of the BL and EL is still requiring 2 HEVC streams to be decoded so in theory I think its the same - unless the Shield is dropping the decoding of the EL and just playing the BL + RPU - not sure how we can tell?

Unfortunately, the single-layer file created by yusesope won't play in my x700( they also stutter on the C8) so I can't really compare properly as i did with TS-DL vs Mp4-DL

Also, with the shield, I cannot go frame by frame making it very hard to compare exactly the same frame.

So i tried my best to go at the same frame...it's close but not identical.. single layer looks brighter and washed out a bit :( this is 4.6 shield vs DL Mp4 x700: https://slow.pics/c/PYlA3TLw
comparison made in a complete black room without any lights.. Camera settings locked.. Tripod and bluetooth triggering.

4.6 is identical to 7.6

The shield is sending a different signal than the appleTV and the x700:
So maybe the difference is because I used 2 different players. no way to be sure.
IMO, the shield just cannot play both BL and EL... so we get BL+RPU
Shield (up to date):

AppleTV & x700:

So if yusesope method ever works on the x700, I'll do a proper comparison

Thanks you very much @RESET_9999

The frame is pretty close, good work.

So we can say thats is not the magic solution unfortunately

Do the Shield and ATV4K look the same, meaning brighter and washed out compared to the DL File?

I never tried my appleTV for DV rips. Does plex support DV as well or just MrMC (i dont own this app)?

Infuse is the best, I think MrMC works as well but Infuse on the ATV4K is solid.
