The Apple TV hacks are coming fast and furious as recorded on both the Something Awful thread we already told you about, and at the Apple TV Hacks blog. Over at Something Awful, user macado shows the Apple TV successfully decoding a 720p XviD clip using the open source VLC player (though only for 6 minutes). Other users have demonstrated Firefox and iTunes running on an Apple TV as well. Meanwhile at Apple TV Hacks, there are already tutorials up on getting SSH and AFP access and even setting up Remote Desktop (VNC) and Apache.
In short, the Apple TV has been busted wide open and is well on its way to being hacked into a general purpose (if rather underpowered) mini Mac mini (Mac nano, perhaps?), running OS X 10.4.7 as you can see above. For those of you with a hankering to break your warranties, it looks like the Apple TV is eminently hackable and has a lot of potential.

Update: the 6 minute thing has to do with the fact that the Apple TV automatically resets after 6 minutes (see the comments below).
