Now that we can jailbreak the Apple TV, we just need apps on it. The app is called nitoTV and it’s basically a front end for the mplayer media player. It also includes additional capabilities to view RSS feeds, weather forecasts, and more.
I’m not sure how they got this app in there. All I can tell from nitoTV’s Twitter account is that the app got copied over using SSH. There’s probably going to be more to come in the near future.
