I've recently noticed that bluray titles (ripped to .mkv) will have
significant video juddering / skipping when the TrueHD audio track is
used. Switching to the 5.1 track will stop the judder. I don't see
any issue when playing something with other high resolution audio
formats (DTS-MA).
I've set the audio read ahead from the default 100ms to 500ms and saw no change.
I'm using a Nvidia GT 430 and driver version 340.107.
Mythtv version (compiled myself):
mythfrontend --version

Log file from a play back with playback,audio flagged:
https://pastebin.com/z8dcxcCz
In this log there are two playbacks. The first (using Shazam) is
default with TrueHD. The second time Shazam is played a few seconds
in I switch to the 5.1 track. The juddering video becomes smooth as
soon as 5.1 is selected.
I've verified this behaviour with several different movies that have
TrueHD and also movies with DTS-MA (and the DTS-MA titles play with no
issues).
Has anyone else experienced this?
Thanks!
Neil
