its more of a slight tearing, I get it with avi(xvid) files but not
mpeg2 files (not using XvMC), i really don't understand why, I think
it may be due to Xv scaling. I notice it with this card on my 21"
monitor as well. It sounds like I'll need a new video card anyway for
the Dual-Link DVI port since I know this card doesn't have it.
