i have an Apple TV, it worked fine for a while. Now I cannot see any of the movies i downloaded from itunes. I can see other short movies from Goggle and free podcasts from itunes but not anything i purchased. When i select a movie, and they all show up , including those i purchased from itunes on the tv screen, it begins loading with the little spinning dial on the TV screen. The i get a message that says the movie is not authorized on Apple TV. Anyone else have this problem. I have my itunes on a PC. My son has a Mac and his works fine on the same TV. We have a wireless system that works fine and I can see his itunes library on my PC since we have sharing.
