Hi,
Strange results here. I tried mplayer playing both audio only and
then some video recorded with MythTV. No segfault problems with either
one on my end but on the video (Tonight Show) the audio was very
clearly out of sync with the video.

To check it out further I tried watching the same clip in MythTV
and got a crash:

Looks like there is a bit of an issue here.
