Finally, we can access iTunes Extras for HD movies on the Apple TV. Previously, the only way to get them on the Apple TV is to AirPlay them from iTunes on a Mac. The new iTunes Extras play from the cloud, so new videos and features can be added regularly. In my case, I can get the new iTunes Extras interface for supported movies on my Apple TV, but only if I play movies from the Movies -> Top Movies, Genres, and Search sections. It won't work if I play the movie from the Movies -> Purchased section or via Home-Sharing from an iTunes Library on a networked Mac. I'm wondering if that's really how it works now or if it's just me.
