The Apple TV has been updated to software version 5.1.2 with fixes for a number of security bugs, but the big news in this update is the Hulu Plus app which has been completely redesigned.
When opening Hulu Plus, content categories can be found across the top of the screen, separating TV, Movies, and Kids programming for quick access. There is now a “Shows You Watch” section on the first screen of the app for easier navigation to the programs you watch regularly. Hulu also added a couple of small but very useful tweaks for controlling playback. First, when you find the show you want to watch, just highlight it and press play to start playing the latest episode. Finally, during playback, hold down the “Select” button on your Apple TV remote to bring up the Subtitles and Audio options.
To update your Apple TV firmware to the latest version, go to Settings > General > Update Software.
