Hello! I am irrated about what is going on with my bluray rips. I convert a MKV to MP4 using handbrake with the apple TV 2 preset. It works fine. I usually play on my apple tv and somtimes my Mac Mini with HDMI out connected to bose 5.1 using the headphone jack. When opening my videos it would automatically go to stereo and I could right click and switch between tracks to stereo. Now, I opened a movie I was able to switch back and forth and its GONE! Its grayed out and I can't even click it! I am so confused about a week ago I could switch within iTunes and not any more! Can someone help?
