The pioneer doesn't have a tape out.
I'm not sure if theatertek would work with 2 cards or not?
I got busy when making my post that I guess I left out that I have a denon 3808 that I use in my theater.
So really what I am needing to do is go from HTPC--7.1 analog to Denon, then I was going to split the analog to the pioneer over to the 5.1 (as I don't care if the stereo zones lost the extra surround channels), then get it to stereo into the nuvo.
I am a fellow CQC user so what I am trying to accomplish is that if we are having a party or something people could watch a movie in the theater in all of its glory, but if you were out shooting pool in the rec room you could turn on the lcd on the wall and listen to the sound over the nuvo.
It's my only biggest issue with all my setup. Everyone comes over and finds the nearest touchscreen and starts turning stuff on, then have this glazed look when I say "yeah but you can't listen to it here in the is room"
Doing some reading it seems that the tape out might work, which I am not opposed to getting another receiver. I just wish I knew for sure it would work. I was really surprised that listening with the headphones didn't work.
