Ok i edited this text as my friend had the same problem and resolved it by uninstalling and reinstalling itunes.
I had another question, when i add movies to the iphone, some have a black screen as the thumb and thats how it shows on coverflow, i have tried adding a picture by going to the bottom left of itunes and when drag and drop the photo i want on coverflow there it appears for a few seconds but as soon as i close itunes or change file it goes back to the normal black picture for coverflow.
how can i put my own picture for the movie file to appear on coverflow.
