I have a Sony RM-AV2100 touchscreen remote, which was working just great until I got my new Denon 3802. I used code 027 for the receiver. Using this code, I can turn the power on and off, adjust volume, and change some of the inputs. However, the DVD and TV input buttons don't work. And for some reason, the remote won't let me "learn" those two functions. All the other functions are learnable except for DVD and TV input selection. Does anyone know how to get this thing to work?
