You probably have not had a response because there are so many Threads/Post for Panasonic Plasma's which most of them should tell you that the Codes have been the same for all models worldwide for years (maybe just a few new functions) and links to this
PDF. I would suspect URC would have these codes in their database, try other models.
As far a the Diginet goes try other models or learn them from the original remote.
