I have a Panasonic PT-50LC13 TV and a Motorola DCT6416 III DVR provided by my cable company. There is a button on the Panasonic "universal" remote control to operate a CBL box. I would like to use the Panasonic "universal" remote control to operate the Motorola DVR recorder/tuner, but there aren't any codes in the instructions that correspond to it. (The TV pre-dates the Motorola DVR.) Can anyone tell me what conversion code will allow me to operate the Motorola cable box/DVR using the Panasonic remote control?
