Q: I rented a movie on my iOS (iPhone, iPad or iPod touch) device, how can I watch it on my computer, Apple TV or any other device ?
A: You may play your rental on more than one device, if you download your rental movie on your computer. You can move the movie between different devices like Apple TV, iPhone, iPad or iPod. However if you download a rental movie on your iPhone, iPad, iPod or Apple TV, you can not move it to another device, such as your PC, Mac or other iOS devices. However you can still watch a rented movie on your TV via Apple TV and AirPlay.
