I completed a fresh install of Win XP pro on my machine about 2 months ago. I installed the lastest drivers for everything on my computer and also installed windows media player 10. When I play back .mpg or .mpeg files, they look pixelated and grainy, with an overall "bleached out" appearance in color. When I play these same files on other computer, that is connected over my LAN, they play fine. The files are a collection of music videos and various funny clips that I have recieved via e-mail over the past 5-6 years. I did not create any of these myself, so the issue has nothing to do with capture or encoding. So far, I have rolled back to windows media player 9, tryed installing new codec's (divx), and basically am stuck now. These files worked fine before the install, and honestly, I do not remember if they did not work right after the install, I just recently saw the problem. My system stats: DFI board- infinity nforce 2 AMD 2500+ 1 gig PC400 DDR RAM Geforce 6800 (Asus V9999) Ultra - 256mb RAM System runs cool - 41.5 C degrees maximum on CPU, never overheated Games and everything else run perfectly. Graphics in game play flawlessly, no artifacts or anything at all to complain about. I get the same problem when I play the video's in realplayer, so I believe the issue is now either with the codec's installed on my system or it has to be a conflict? I have the newest Nvidia Drivers, I tried rolling them back to a perivous version with no success. Thought this info might help?!?!? The playback basically has a "haze" or "halo", which means watching clicks unbearable! Any thoughts?
