Try the discrete codes for the Pioneer Rear Projection tv's in the files section here. I've been able to use them to control the older elite tv's....especially since the pronto won't learn the codes from the actuall remotes. If you're using the TSU2000 or RC5000i (using the Touchscreen editor program) try setting the IR codes by using the program's builtin database, I've gotten those codes to work with those TV's also.
