I have to smile as it sounds like you are going through a steep learning curve with Denon - just as I did
If I can remember correctly I downloaded one from Remote Central and kept it in the back ground and created some new buttons which had very basic macros for things like turn on/off or watch Sky/dvd/tuner/cd etc on another screen which worked with my projector and quadscan. It's like all these things eventually you only use a couple of regular buttons on the Denon and it was easy for the family to use if I created one new page in the Pronto to deal with these fewer choices.
I've got a Denon 3802 and 2800(dvd) set, and a TSU3000/950 pronto. I went to the pronto sit but all the config files relate to different remotes, not one is for my remote, or is there something I am not aware of in the naming of the files?
