Has anyone else had issues playing rented movies on their Apple TV? I've rented ~3 movies and each one has had the same issue. Once its downloaded enough to start playing, I get the popup that says I can start it. Once I start the movie, all I get is a gray screen and no sound. I can exit out and try again with the same result. Fast forwarding/rewinding doesn't do anything. The only fix I've found it to reboot the atv by unplugging it. Once it boots up, the download resumes and I can play the movie w/o any more issues. I've only tried HD rentals so I don't know if I would have the same problem with SD movies. Besides this, I have no issue with my atv. Anyone else seen this or know how to fix it? Thanks!
