Just overhauled my computer a few days ago (new mobo, processor, vid card, and hard drive).
Only now all the movies I watch are verrrry dark, but I've played a few games (DoD, NS) and they look great. So I figured this was a codec problem, and downloaded the k-lite pack, but there was no change. So this morning I downloaded defilerpak, and again no change. I also got the divx codec before the k-lite pack.
Anyone know what else I should try?
