Not sure I'm in the right Forum but here goes. I have a 2012 Mac mini hooked up to a television with several movies stored on the hard drive. The movies have been processed through Handbrake. My stereo is across the room and I want to stream the audio from the movies to my stereo using an Airport Express. But Airplay will only let me stream music from iTunes. Is there something I'm not doing correctly or am I limited by iTunes or by my first generation Express?
