HEY THANKS, I am hearing a lot of good things about the onkyo series receivers, my parents had one along time ago and it is still alive in our cottage. I do want to get two hdmi outs or I guess I could use a splitter, space and presentation are a bit of an issue. Sorry i'm pretty green when it comes to audio and I notice a lot of people using mac's as a secondary driver. How exactly does that work, connections and interface with another receiver.
