The core issue is that mythtv player is very poorly designed here. It uses
a single ring buffer, demuxing data as it comes in. If the frame demuxed is
a video frame it will decode it, if it's audio then so be it.

If the container doesn't contain properly interleaved data, then it will
decode a lot of video and by that time the audio may underrun.

It should have two different streams, one for audio and one for video.

The entire architecture of the player sucks anyway, it's beyond
