I have got many saved videos in my computer and not all but some of them when I open up in Windows Media Player 11 then the screen goes totally solid green. Although the audio seems to be playing fine but the video is not at all visible due to the green screen. Also, sometimes some errors from microsoft pops up on every other attempts when opening a file and I have already send those error to microsoft. Can anyone tell me how to fix this green screen error? Thanks.
