[mythtv-users] Audio stuttering during 1080p playback

[Darren Black]

FYI I experienced this issue in mplayer some months back (at that time I was
forced to use mplayer to watch h264/AC3/mkv files). The most recent release
of mplayer fixed the issue... I am sad to see that it is present in the
current release of myth.

Again, it only occurs with DTS streams.
