On my xbox 360, games run smoothly 100% of the time but when i try to play DVDs i run into trouble. the view will alternate between clear reception and a state where suddenly the color is screwed, the audio is unclear, and sometimes the screen goes completely blue as if the xbox was turned off (although the audio is still there). a photo of what the screen looks like when it's acting up is available at http://img297.imageshack.us/i/img0513v.jpg/ any ideas at how i can fix it?
