How to stream music, movies, and TV shows to the Apple TV with iTunes in the Cloud

iTunes in the Cloud allows you to stream a lot of your purchased content right to any Apple TV in just a few button presses. This includes any tv shows, movies, or music that you purchase. That means there's no need to burn anything to a disc or AirPlay from an iOS device, as long as you've got an Apple TV.

It's worth noting that some movies and TV shows may not be eligible for streaming. This is typically due to licensing agreements between Apple and whoever released the content. Sometimes movies that weren't previously available for streaming may simply show up one day. Unfortunately, the opposite can happen as well, though it rarely does.
