OK, now that's weird.  With that command line, mplayer clearly doesn't
like the file.  Yet I can "just play" the file with myth, mplayer, or
smplayer and see nothing wrong.  I just played the file with smplayer
now, and used the scrollbar to jump through the file, and everything
looked good through the end.  I just looked at the window I started
mplayer in, and there's a fair amount of hate-mail:
mplayer /media/1006_20100303200000.mpg
MPlayer SVN-r29796-4.3.4 (C) 2000-2009 MPlayer Team

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

As is often the case, the family's asleep, and I'm doing this with the
sound turned off.  I just turned if on.  When I try to play the mpeg
file directly with smplayer or mplayer there's no sound.  When I go back
into MythTV and play the same recording, there is sound.  I'm sure this
is logical to someone who understands this stuff, but certainly not to me.

Thanks,
Dale
