The update also offers three new screensavers--Cascade, Shrinking Tiles, and Sliding Panels. You access them through the Screen Saver command in the Settings screen.

Within the Trailers app, you now have the ability to search your local area for movie times. In the U.S., launch Trailers, navigate to the Showtimes command, enter your Zip code, click Submit, and local theaters appear. Select a theater to see what's playing. Choose a movie playing at the selected theater and you can see its showtimes. On this same screen you'll find other theaters in the area also showing the selected movie. Choose one of those theaters and you'll see its show times.

The update also includes the option to rearrange icons for third-party apps on the Apple TV's home screen. (You can't rearrange the Movies, TV Shows, Music, Computers, and Settings icons). For example, select Netflix and hold down the remote's Select button. The app's icon will begin wiggling. Use the direction buttons on the remote to move the icon to a new position. When you're happy with its placement, just click Select again to plant the icon in its current position.

Finally, the 5.1 update adds support for SDH (Subtitles for the Deaf & Hard of Hearing) subtitles. Apple also claims that the update includes general performance and stability improvements.
