Important Apple TV 3.0.1 Update to Prevent Temporarily Disappearing Content
If you've installed the Apple TV 3.0 software update, you should immediately update to version 3.0.1. This prevents content from temporarily disappearing until it is resynced.
To update your Apple TV software:
1. Reboot your Apple TV (unplug the power cord and plug it back in)
2. Select Settings > General from the main menu
3. Select Update Software
4. Select Download and Install
Note: Your Apple TV will conduct a restart, which is followed by the Apple logo and a status bar.
