Apple TV owners got some love after iTunes 8.0.1 update, in the form of Apple TV 2.2 update that adds a number of new features that some Apple TV users have been waiting for since its release. According to an update page detailing the changes of the release:
Apple TV 2.2 adds some basic playlist functionality like Genius playlist and On-the-Go playlist creation. But forget making music playlists from your TV. More importantly, you can now create playlists with music videos in iTunes, playing them continuously on the Apple TV! Those who like to entertain guests in the same room as the TV knows that music videos would be way more entertaining than just a stupid music playlist, right? I have at least one friend who is going to die of excitement once he sees that one on the list.
In terms of new features, Apple TV 2.2 now lets users purchase and download HD television shows directly from the media hub, most of which are priced at $2.99. Previously, Apple TV only included support for browsing the iTunes Store's collection of standard definition shows.
