Purple tint/overlay during video playback after gaming

Hello,

I have noticed that after playing a game of counterstrike source, when
I use wmp10,11,vlc,in browser,quicktime plugin that there is a purple
overlay. If I use media player classic, the video plays fine. I have to

restart the pc if I wish to use the other media players without the
purple overlay.


I have a 7800gtx 256, 1.5gb-ddr2, p4-3.0ghz,winxpsp2retail. It's really

annoying Please can someone enlighten me on a fix if one exists. I
beleive media player classic to be the better player for videos, so im
not that fussed about using wmp10/11 for video, but still the problem
with viewing videos through the browser, like aaple.com/trailers


Cheers for your time...
