Sorry I'm still very unclear of what each will be doing. The only advice I currently offer with the limited information is to get a universal remote with a rf to ir receiver and assign the ir outputs for each. That means you would have 2 yamaha AVRs in the remote control. I'd expect this may not be feasible as there aren't many choices that are inexpensive and most require a dealer program. Havent looked to see if harmony remotes can do this, but RTI, URC, Crestron, and other higher end remotes.
