Plex isn't the only one bringing a fan-favorite media app to the new Apple TV. Jean-Baptiste Kempf has quietly revealed that VLC, VideoLAN's signature media player, will reach Apple's latest set-top box. It's still early, but this could open up your playback options for music and video -- you may have more choices for formats and sources than you get out of the box. While you aren't going to get total freedom (you certainly won't be playing DVDs on an Apple TV), this beats having to rely primarily on streaming services.
