One of the best hacks to come to the Apple TV in the last year is PlexConnect, an amazing little program that hijacked the Trailers channel on your Apple TV and connected it to the Plex home media library running on your Mac. What the hack meant was that you could stream your Mac’s entire video or media library to your Apple TV just by navigating with the remote… no AirPlay required.
It was wonderful, but Apple doesn’t like hacks. That’s why PlexConnect is now dead. (Update: It’s back!)
