Plex is without a doubt one of our favorite Mac media center apps. So it's with wide-eyed interest that we tell you about the Plex client making its first tentative steps onto the second generation Apple TV platform. Naturally, Cupertino's not behind the initiative to replace Apple's own "Lowtide" 10-foot user interface -- this work is being done by the Apple TV jailbreak community. The ATV2 build is still just a proof of concept so it's buggy and limited to video playback (no music, images, or app management) for now. But hey, it's another iOS app for ATV2 and it does work as evidenced by the video after the break. Man, we're getting all tingly at the thought of scattering a few $99 boxes around the house to serve up the wide variety of codecs supported by Plex in addition to Apple's more limited AirPlay.
