That's very strange.  If you just feed mplayer an mpeg2 file does it still
do this?  If not, then try this:

cat /dev/video0 >/tmp/foo.mpg # or /dev/video1 or whatever
^C # after a few seconds
mplayer foo.mpg

Do this without your xawtv workaround.  Does it still screw up?  Can you
transfer that foo.mpg to another machine and see the same problem?  I'm
trying to figure out if this is mplayer (or maybe your video driver) or if
it is the driver.
