Well, the ATI player software for Windows which of course uses all the nifty
features in the chip *does* produce a better picture, but I can't tell whether
it's due to the HWMC/iDCT or some other stuff like post processing or
filtering the chip does.

Guess I'm gonna make a screenshot with ATI/xine/mplayer if I find some time
and compare.
