Apple has sent an email to customers asking them to immediately upgrade their AppleTVs.
There is an issue with Apple TV software version 3.0 that can possibly cause your content to disappear after a period of time. All customers running Apple TV software version 3.0 should immediately restart their Apple TV and then upgrade to Apple TV software version 3.0.1.
