Ok so I had a pretty good collection of videos (both bought from music store and others i put on myself) on my itunes and ipod. then recently I downloaded and updated to itunes 7 and suddenly I found I could no longer watch my music videos in itunes or put new ones in (when i try to drag them in it acts like its going to work but in the end nothing happens) so then being the idiot I am I decided to connect my ipod and inn the process of updating it all of my videos both music and normal off of my ipod. can anyone tell me what im missing (right now I really am hoping I just overlooked something stupid and my movies are really all right)
Thanks
