Green screen and it looks like a nagative

Hello, when i try to play some WMV’s the screen will go green and the file will play but it will look green, blue and purple.. It almost looks like it is playing a nagative of the file. This also happens when i try to stream live video. I have tried to download new divx pro codecs along with some other files i found under the “green screen” topic. Hope someone can help!

Thanks
