It's a home theater receiver, probably 6 or 7 years old. Guess I can't fault URC for not having the codes - I can't even find a reference to the unit on Denon's web site. Amazon still has a page for it, but of course you can't order one.

Surely I'm not the only guy here with this particular unit? I found a file over in the Pronto section that has this unit as part of a Pronto file, but I don't know if I can get that into this remote.

Although now that I think about it, I have an old Pronto somewhere that still works. Guess I could download the file and then use the Pronto to teach the MX950.
