Hi all. I am setting up a URC MX-450 and would like to know which code set I should be picking for a Denon 1907 receiver? I have picked a few and they don't seem to have all the functions setup. (second zone, and iPod input are a couple). I understand that i could "learn" those code, but i thought that if there is a code set that already has those it would save me some time. Thanks.
