Apple late last night issued iOS 4.2.2 (It’s actually 4.3, but Apple TV updates are numbered differently ) update for the current-generation Apple TV. The update specifically addresses a number of minor bugs, such as audio and video output problems experienced with some content.

Here’s the full list of fixes from Apple’s release documentation:
- Audio: Addresses an issue in which audio is not output when playing some video content.
- Video playback: Addresses an issue in which video is not displayed when playing some content.
- Audio output setting: Adds an audio output setting for switching to 16-bit audio for compatibility with some TVs and AV receivers.
- Live FF/RW improvements: Improves the performance of fast-forwarding and rewinding live events.
- Movie description: Addresses an issue in which the description information is not displayed for some movies.
- YouTube video order: Addresses an issue in which YouTube subscription videos were not ordered by date.
As usual, you can get this update over-the-air via the settings menu on your Apple TV.
