iTunes 11 (Windows 7) Movie Freezing.

[Jimrod]

Hi guys, just wondering if anyone else is experiencing this problem - basically I have a hard drive full of films (USB, not on PC hard drive) which I can play from no problem at all. I imported the movies from there into iTunes 11 and they show under "Home Movies" but if I try to play one iTunes freezes instantly and will only end by going through task manager.

Any ideas? All the movies are MP4 and play fine in every other program.

Thanks for any advice.
