Current using a WDTVLive in bedroom. I use Mezzmo for video and audio streaming from a server in the house with 21tb of movies/TV/music. I can stream without using iTunes and want to continue to do so. SO...... If I get Apple TV for another room, will I be able to stream video (HD and SD with Dolby DTS, etc) through the Apple TV without having to adding all the content to iTunes? The documentation for Apple TV is extremely sparse. The only use I have for iTunes is updating firmware on my iOS devices.
