There was a movie my wife was wanting to watch, Knight & Day, and when I go into iTunes it won't let me rent it in HD but says that option is available on the Apple TV or iPad. There's the problem. We have 2 Apple TV's and 1 iPad and watch movies on all three. This particular movie she wanted to watch in the bedroom, but I had rented it on the Apple TV in our "Media Room" so we couldn't see it on the one in the bedroom. My question, can you rent the HD content from within iTunes on a PC and view it on the Apple TV? If so, how? Maybe I'm just stupid, but movie after movie keeps showing me I can rent the HD version on the device but not from within iTunes on my PC. Pretty lame setup if that is the case since we have 2 of the devices and don't want to get tied down to watching movies only on the device it was rented from just in case we rent something and then decide we would rather watch it on the other television.
