Hi guys, I'm having a strange problem with a DVD I ripped with Handbrake into m4v format. The video plays perfectly in both Quicktime and VLC, but when I import it into iTunes it refuses to play. It sticks on pause, and pressing play does nothing. I can pull the progress bar to various points in the movie, which displays the picture for the corresponding time, but again refuses to play. Any ideas, as I am tearing my hair out! EDIT: Forgot to say, I have tried re-ripping and encoding the movie again from scratch, and get exactly the same problem.
