Well, you give very little information, especially MPlayer output
is missing. You also didn't say which X driver you are using.
Thus, I can't exclude that it's MPlayer's fault, but I
think the most likely cause is simply that ATI's driver is crap.
Try
1) getting a newer driver
2) using the OpenSource driver (if available for your card)
3) use -vo gl:yuv=2 or similar
