If you rent content (movies in HD) in this case, on Mac, can you watch it on Apple TV? My. Y gaoal is, i have multiple Apple TV's in the house, and since Apple retricts to one device, if renting from that same device..... I was thinking of renting it through on my Mac instead. That way, anyone loogining into the same account would see i have rented this title and watch on the other Apple TV device.
