Thanks Posde! Now I need to go find out the MAC ranges for these Onkyo devices. Google is my friend.
OK, now to add more work for this upcoming weekend. How do I get my orbiters to control it? I want the volume control to control the volume on the receiver and I can't create a media scenario because my Onkyo shows up in red when I attempt to add one. It also doesn't show up on the wizard when I'm trying to add it to my living room. I'm obviously missing something in the configuration but, for the life of me, I can't find it.

I did manage to "resend codes" to it and get it do do various things.
