I have tried MPlayer versions 1.0pre6, 1.0pre7, and cvs from today and
they all work fine under 2.6.14 and 2.6.14-rt21/22.
I booted into 2.6.15-rc7-rt1 and the same MPlayer binaries segfault on
every video I try and play. Yes, I have nvidia modules loaded, so won't
get much help, but thought someone might like to know.
xine plays the videos fine.
BTW, other than MPLayer problems, everything else works great.

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:
