Jim,
I've successfully set codes to those "virtual" devices and then keymoved them to hard keys. I haven't been able to set the remote in a "virtual" device mode yet.
Looking at the RDF file, it appears that there is a memory range set for those devices (well duh, how else would they be there!) and that the remote can indeed handle 15 devices. What is needed (I am just guessing here) is for those device buttons to be set to their proper range, so IR can select them. The RDF file posted is just a beta and I suspect some tweaking can bear some fruit. I played around unsuccessfully to guess the proper key address. That's my extent of programming know-how. I'm sure that others will know exactly how to get to them.............in time.
