Here is my situation. I have a couple seasons of some tv shows i purchased through iTunes a couple years back. Now when i go to play them it says "This computer is not authorized to play this show. Would you like to authorize it?" Then i type in my apple id and password and click authorize. Then it goes on to say "This computer is already authorized." Then it comes up and plays a gray screen with no sound. If anyone can help me it would be much appreciated because the apple store couldnt even help me.
