I have the same problem! Is there anyone out there with an answer! I'm so extremely frustrated with this issue. I did everything that others have suggested on this community and others online. I used a converter (which doesn't even make any sense because I used to be able to drag/drop mp4 with ease without converting them before this stupid iOS5 and Itunes update). I renamed the file to m4v. There's tons of stuff I tried and still nothing. What frustrates me is that everyone is suggesting to convert and as I said I never used to do that with MP4's before. Why all of a sudden now?
