"A few of us here at TUAW received an email from Apple this morning stating that Apple TV-compatible versions of previous iTunes LP purchases are available for download."
If you purchased an LP prior to the release of Apple TV 3.0, then you have to download it again and Apple is now offering those downloads.
According to Apple, "With the latest versions of iTunes (9.0.2) and Apple TV software (3.0), you can now use iTunes LP on your Apple TV. We have updated the iTunes LP that was included with [your previous purchase here] so that it can now be viewed on Apple TV in addition to your Mac or PC...."
