I was running windows vista on this computer with no problems, video looked amazing in SD and HD, I decided to install Windows 7 RC and for some reason Video has very mall lines and squares that, even though you are watching HD, distort the image, more noticeable on faces. This happens on every player, even on my slingplayer which is the one that I watch the most. I installed back vista, and everything perfect, but would like to keep windows 7. Im Windows 7 ultimate RC with NVIDIA GeForce 8600M GT with the latest drivers from Nvidia.
Ive tried everything from messing around with control panel to installing codec packs and latest direct x with no luck. Curious thing is that HD from you tube and apple trailers look good!! Can someone help? thanks
