Apple has just released a minor iOS 4.2.1 software update for the Apple TV 2G. It addresses an issue that causes some high-definition TVs to incorrectly display at 480p as well as an issue that may cause a movie or TV show to be re-downloaded. The build which is marked as iOS 4.2.1 (8C154) is reported by Apple TV as software version 4.1.1. The previous Apple TV iOS 4.2 was Build 8C150 and it was reported on the device as 4.1. According to nitoTV, it appears that SettingsAboutViewController grabs the “software version” number from the Info.plist inside of AppleTV.app rather than [ATVVersionInfo currentOSVersion] which is why it listed 4.2.1 in 4.2 and 4.1.1 in 4.2.1. NitoTV also confirmed that tethered Jailbreak for 4.1.1 still works “just fine”.

Fire Core has finally released the first beta version of aTV Flash (black) for the Apple TV 2G. It gives you a web browser with HTML5 support (not all HTML5 sites are supported yet), a Plex client that lets you stream nearly any kind of video from Plex Server running on your Mac, Last.fm access and some info on demand (current weather and news feeds). Fire Core promises to enable additional media formats such as AVI, MP4, MKV, DVD files and to support media streaming from most NAS devices (including Airport Extreme and Time Capsule) in the near future. You don’t need to be worry about the original Apple TV features, they will all remain fully operational.
It’s been a few days since this hack came out, but there is a chance you’ve missed it focused on your Thanksgiving and Black Friday activities: a jailbreak app called AirVideoEnabler can push out video from any iOS app (including Safari) to the Apple TV 2G via AirPlay. Developed by TUAW commenter Zone-MR, the app runs on every jailbroken iPhone, iPod touch, or iPad with iOS 4.2 (or greater) installed and can be downloaded from Cydia for free. According to Lifehacker, you may need to restart your iOS device for the hack to work, but then you can stream supported video (meaning most MPEG4/H.264 files) from any app that supports video out. Users report that thanks to AirVideoEnabler they were also able to stream live TV to the Apple TV via AirPlay.
