I purchased the newest apple tv recently.  Anyways, when I tried to stream a movie that I had ripped and placed it in my library, it will take over 15 mins for it to play.  On the other hand, I would copy that exact same movie to my ipod touch, it would play almost immediately.  From what I had noticed, airplay is faster than pulling media from my itunes.  Does anyone know what is causing the lag?
