MakeMKV (1.17.1) can not open any BD/UHD BD when it does have PCM & DTS-HD MA Audio at the same time. I always get this error:

Failed to decode audio/video data for title #7 - invalid mux or internal error, title skipped.

Had this already on another normal BD and now on this UHD BD. Since the UHD BD does have DV going with MKVToolNix is not an option as it can not handle UHD BDs with a seperate DV Stream.

I can reproduce the issue 100% everytime on the UHD BD of "Das Piano (Special Edition)" with PCM Sound. Here a link: https://www.blu-ray.com/movies/The-Pian ... ay/315874/

I even tried to first mux it with MKVToolNix and then pipe the MKV (without PCM!) to MakeMKV. But this results in:

Hack: Found secondary video stream with RPU, assuming DV EL
Hack: Attaching DV data from second video track to first one and discarding second video track

Failed to open disc

Please fix this

Ok, after some testing I found out that it is NOT the PCM Audios that cause the error, but actually the UHD Video.
Don't know why..

I have tested the UHD BD itself and for validating there is something wrong I also tested some "Scene Releases".. none worked.

Same issue as viewtopic.php?f=12&t=28701

True, did not notice this thread. Thanks for pointing it out. It even is about the very same UHD DISC.

Was this ever resolved for you? I'm having a similar issue on the Criterion release of The Piano. No luck with the latest MKV version 1.17.2
