You should look into a Universal Remote. You Should look at the MX-850 or MX-900
The remotes retail around $400-$450 depending on where you buy it from. Also Is the equipment in a cabinet or behind a closed door? Do you want to use RF? If you want to use RF you would want to get the MRF-300. This is an RF Receiver unit with emitters and Antenna. This unit retails for around $200.00. I'm not quite sure how URC is controlling the programming these day's, but I think you have to register the remote to get the program.
With Programming Macros, you can have the one button operation. Take a look at pro-remotes http://www.proremotes.com they sell and program the remotes. you can also look at surf remotes [Link: surfremotecontrol.com] I'm not sure if they do the programming also, but I see there names on these post quite often.
