Guys thanks so much for the replies. Newbie me, I thought I would receive an email if anyone responded. I just checked the thread and saw your responses! I just noticed the check box for "notify me of replies." Now I am in the loop.
Matt: After talking to the mfg (Z-Systems) a while back, they said that Harmony remotes had the RDP-1 codes in their database. So I bought a Harmony 1100 on Craigslist, programmed it from Harmony's database codes, but all it would control is a handful of functions on the RDP-1. Maybe the codes were only partial or something. So I do need another way to do this. If you can help you would be an audio hero! Let me know what you need me to do in order to give it a shot. I will obviously pay for whatever you need, in addition to the wine/beer!
Happy holidays everyone.
