Whenever I playback video I get part of the video cut off with black borders. It does it on video playback and TV also. I thought it might be an over scan issue from the ATI card however I've adjusted that and the screen fits the TV fine. When the black borders appear you can see the video fits the screen correctly but it just cut the edges off the video. I say this because the TV logo is in the right place just half it is missing with black borders going through it. It will also adjust the black border size at random intervals. It's so strange since its a fresh install. How on earth can I fix this???
