[mythtv-users] mythtranscode output causes my mplayer to explode

In 0.18.1, in Ubuntu Breezy:

I've just discovered that mythtranscode is producing files that cause
my mplayer to explode.  (I'm running mplayer on my frontend right over
the display being produced by mythfrontend on the PVR-350 there; the
explosion apparently nukes the entire login session, because as soon
as mplayer blows up, I wind up staring at Ubuntu's login screen.  It's
not -just- nuking mythfrontend, because I set up mythtv's .xsession to
respawn mythfrontend every time it terminates.)

These files start out MPEG2 from a PVR-250, and I'm transcoding with
all the default options.  (I've set everything to 720x480, but nothing
else has been changed---not bitrate or anything like that.)

Note also that mplayer first complains that these files have no audio.
It then displays several seconds (5-10) of video, and then blows up.
This has happened on at least two files so far.  I know that not -all-
transcoded files do this, because when I first tried this, it worked
enough to at least give me a file with very -quiet- audio (which I
bugreported here but which no one has responded to), whereas now I
seem to be getting files that claim no audio at all.

I'm not deleting the original MPEG2's; playing those is perfect.

Anyone have any clues?  Tnx.
