Hello, is it possible to convert from truehd + atmos to eac3 + atmos and mux with dolby vision movies?
I have not a receiver so I have to stick to ac3/eac3 but eac3 + atmos is so much better than ac3/eac3.

Oppo has issue upconverting hdr10+ to DoVi
why would you do that now that there's a tool that perfectly converts HDR10+ to true dynamic DV?

Firmware update version M43.R.0284 for UBP-X700 | Release Dat 08-24-2021

Removes the Gracenote function
Improves HDMI connection stability
Supporting Dolby Vision content for Blu-ray Disc, Netflix and VUDU
Supporting online streaming services
Have not updated mine yet. Whatever DV support means in the text above. Maybe they fixed the DV limitation where you had to know which movie/disk is DV to manually enable it?
Anyone updated yet and tried a Cinavia protected movie?

haven't updated my unit yet. Which titles have Cinavia? I thought the latter was thing of the past lol

I could be wrong but i think you need the Dolby encoding suite for that and I dont think it's cracked.

EDIT: scratch that. theres an old version on russian trackers. Dont know if it supports Atmos though

Thanks, I thought so. Looks like there is no legal way for this unless you pay around 1000$

Don't products like DVDFab remove cinavia or is it through encoding not just 'muxing' it out or whatever?

Cinavia is already dead. Most studios don't use it anymore. With the introduction of DRM with online streaming and piracy through 3rd-party players, the cost of it no longer was justified. But I think you are right, DVD Fab has the ability to remove it.

The new Fire TV Stick came out today - https://www.amazon.com/dp/B08MQZXN1X/re ... CB5HMB36RE. Wonder if the new GPU/CPU supports more DV profiles lol

I've preordered one for AV1, but the speed upgrade is welcomed.
Any Dolby Vision improvement is a bonus to me.

I tried to find some information about the CPU, but found nothing. Very strange...

Black Widow UHD + P5 = the same exact source/fames/time stamps = all match exactly

L2 meta keep coming out weird.
But on the xml it seem to be correct well (not 100% sure it’s correct.)
What could be the reason for this?
Just curious if u got any insight on this from others ellse were

So far I get a perfect l1DV meta match from resolve min-average-max are all correct
For spares & munsil compare to the original

I don't know, I've mentioned that the L2 doesn't always match in the RPU.
My only test samples are Netflix's encoded streams, and the corresponding CMv2.9 XML.
Sometimes it's fine, sometimes the values are different.
