I'm new to the ATV, and still trying to figure this one out: I purchased an HD episode of a show, using the ATV. The next morning, when I fired up my PC, the episode was transferred from ATV to PC. Fine, nothing against that. Later in the day, when I went to watch the show on the ATV with the PC off, the episode was gone from the ATV. I had to turn on the PC, which then synced the episode back to the ATV. So it seems I can't watch this, or presumably any future episodes on the ATV without also turning on the PC. Not what I was hoping for, to say the least. I have the ATV paired to the PC and using custom sync. I thought the whole point of the newer software for the ATV was that it could be used without turning on the PC (unless streaming). Any suggestions? Is this "expected behavior"?
