Okay so I called apple support and here's what they told me... that there's no way you can just store your purchased movies on AppleTV's drive. Apparently it would automatically sync to your itunes on your mac and generate two copies - one on your appletv and the other on your mac. here's my quams about that (although from a backup perspective it is good)... i'd like to have my mac just for music and work documents and no movies. I'd prefer to use my appletv to store my movies since it has a dedicated harddrive.... is this true? Can anyone confirm this for me?
