Apple TV HD TV show list
Now sure why this update wasn't available at launch, but starting today Apple TV fans can download update 2.2 which among some security updates and Genius features, finally allows you to buy hi-def TV shows from the comfort of your own couch. What's also nice is that it doesn't matter where you buy 'em, because just like when you order a HD show via iTunes, you also get an iPod friendly version.
