Mostly an AVI will be dark in WMP but normal in Media Player Classic, sometimes the other way around, sometimes ok in both if I'm lucky but now, one film is dark in both, which brings me to these forums. =) I think it's DivX which WMP doesn't like iirc and the AVI which was dark in both was an Xvid. How can I alter the brightness or gamma to play these back properly? Monitor brightness doesn't seem to affect playback, it just washes outy everything else. I remember once having black screen playback with Mpeg4 and it was resolved by altering the codec settings. Is there somewhere with the codec, WMP or Windows XP I can alter that might correct this or what else can I do? I use the klite codecs which I've been very happy with until this problem arose.
