hey guys, not sure if im in the right forum with this..
i was wondering if anything can be done to improve the quality of my video playback with what i already have. i'm using a dell vostro 200 with an evga 9500 1gb card and an e1909w monitor, running at 1440 x 900. i think that my dvds and dvd rips should be showing a little bit cleaner than they are right now..i use k lite codec pack, and i find that my playback is still a bit blotchy sometimes. games look awesome. its just my video playback im concerned with...any suggestions?
