Green Screen when playing videos.

[Necron]

Try the codec pack link in my sig - least bloated codec pack I've come across that provides playback for a large number of things

Also, what type of file are you trying to play?

I'm just trying to play music videos on the net.

Ok, I downloaded that, and now when I try to play, I can see a still image with green lines, and i can still hear the sound..

EDIT: Oh, I think the problem must have been something to do with Media Player, because I set the video acceleration to None, and now I can see the video.. So I think it's problem solved.
