If you are talking about Pronto-
The "other" Panasonic codes mentioned above ought to work, but if they don't-
I know for a fact that Denon DVD-2500 (player was Panasonic A120 based) discrete codes work. I recently upgraded from the DVD-2500 to the RP-91, and I didn't have to reprogram my Pronto for any of the codes.
If you are still stuck, email me, and I'll send you my .ccf.
