I can't seem to properly play videos on my iPhone. These are videos which I've synced from iTunes. Every time I play a video, whether it be an episode of The Office or an SNL skit, there is this weird bar of color that blinks across the screen, and the same scene on the screen flashes over and over, and eventually the screen skips to a new scene, which scene also flashes over and over. The audio in the background works fine. What the heck is this?
