[CSOCSO]

Hey... i have a white, maybe green pixel dots on the black frame in full screen, but only when i see the skin!!
if im hide the skin the picture quality is back to good..

its the same at any skin in any mode ( fullscreen and normal)


what would be the problem??? i have win xp sp1 and k lite kodec pack.

i tried the newest (whenU ROXX) Bsplayer.. but... wont help..
