I tried to purchase an hd movie on my computer and got the message that I'm not permitted to download an hd file because my computer and/or monitor do not support hdcp. However, I don't really care if the file plays on my computer as I"m only interested in watching on the apple tv 2. If I make the purchase through my ipad or iphone, can I then transfer it to the computer and still be able to play it through the atv2? Any help is greatly appreciated. Also, I've heard that the hdcp issue only presents itself on windows seven computers. Follow up question is whether I can do the download through itunes on a Vista computer and transfer it over without a problem.
