Photos: A guided tour of Apple TV

In addition to accessing the movies you've purchased in iTunes (or imported to the software from other sources), you can get an overview of the top titles on the iTunes Store with trailers that stream straight off the Web. However, the Apple TV doesn't provide access to the store itself--if you find a movie you like, you'll need to return to your computer, buy it in iTunes, and wait for the download before you can enjoy it on the Apple TV.
