Thanks for the info. I solved the audio issue with movies (it was the audio settings withing XMBC). It now locks on to the DTS, Dolby, etc signals and switches as needed. I'm back to 5.1 glory for my movies!

Only thing left is 2.1 for music. It seems I cannot figure out how to get the subwoofer to come into play with 2 channel signals. I've been trying to figure this one out for a couple years now. With the in/on wall M22's the sub would come in handy!
