Having same problem with the same Panny Plasmal; can't find a workable code. With regard to a remote that will control both the Panny and the Comcast (standard) 3-device DVR controller, I have successfully used the Monster Cable AV100 and believe, since the AV100 is based upon a Logitech 880 that the on-line programmable Logitech controllers will work as well. I would still, however, like to find workable Comcast codes so I can do-away with the AV100
