- this has worked for some rentals:
- connect your device to your computer.
- In iTunes, select your device (below Devices):
- Click the Movies or TV Shows tab, depending upon the item you rented.
- Select the rented item.
- Click Move.After you transfer a rental, it’s removed from your iTunes library.
Some movies and TV episodes in the iTunes Store are available for rental in HD-quality format. HD rentals can only be transferred from your computer to iOS devices capable of viewing HD content. If you rent an HD movie with an Apple TV, you can’t transfer it to another computer or device.
A rented item expires 30 days after you rent it or 24 hours after you begin playing it, whichever comes first. Expired rentals are deleted automatically.
Note: These terms apply to U.S. rentals. Rental terms vary among countries.
I recently rented a movie to my macbook pro.
First I tried using my VGA adapter to view it on a bigger screen but NO! Don't understand the logic behind streaming rentals using Apple TV on to your TV but you can't use a VGA adapter. So thats another £100 I got to spend to watch content with freedom.
And then after more hours of searching for an answer I discoved when you rent a movie its not downloaded to every apple device.
So I ask the question after paying £3.49 to watch a movie off Itune you'd expect to be able to view it on every device using Icloud but no. Just doesn't make sens.
Justed watch a video saying this is the easiest Itunes player ever. I don't think so... Took me ages to find where the rented movie lived in Itunes. I just think Itunes is a media jail, that you want to escape from!
