Hello all! I have what I think is a very unique issue. Let me start by laying out the system: AppleTV 3rd generation via HDMI to a Pioneer VSX1120 receiver. Mid 2010 Mac Mini via HDMI to the receiver (its my HTPC for surfing the net and working). The receiver is outputting to a 55" Samsung LED via HDMI iTunes media/library is stored on a 2TB time machine After I turn on the AppleTV I normally select my iTunes (by selecting computers) library in order to watch one of my handbrake ripped DVD's. any time I pause, or otherwise change my viewing (switching to my purchased movies, or Netflix) the Mac Mini will start playing music via the inboard speaker. I then need to switch inputs and stop the music by pausing it. If I use the ATV to watch Netflix or stream my purchased movies from the iTunes Store I do not have this problem, only when streaming from my iTunes library. Anyone with ideas on how to stop this would be a life saver. Is there a way to simply play a movie directly from the time machine even if iTunes is not running (this means my home sharing is turned off)? Thanks!!!
