Hmm, sounds like the same problem which i have with a matrox
card, where the XFree86 driver without the binary hal module
has a problem.

This is an 'workaround', which i use for my matrox card, to
allign the video output more nicely for the card with:

 mplayer -vf expand=x:y file.avi

where you have to ajust x and y to some sane value.

e.g. if the output is 640:352 when you should allign it to
640:360. It has to be a multiple of 18.
You don't need to use all dimensions, you can use -vf expand=0:360
for above example. See the mplayer manpage for more informations.

Btw, the x11 output should not have this problem.
