Truthfully I really don't know what went wrong. I was cleaning up my computer and uninstatlled some things and deleted some things then I defragmented the drive. So I go to watch TV, I have a TV Wonder Pro, and the video is in negative. So I go to my Windows Media Player and that is also playing all my videos in negative. Now I'm sure I must have deleted something, but what it is I don't know. Can somebody/anybody help me please?
