Thank you SO much for your help! That didnt work but you did lead me to the culprit. Turns out In all the frustration I never turned off cec in the new bluray. Now that its off, the denon is no longer switching inputs. How in the world a bluray connected to a tv is making its way back down to the denon to switch its inputs is beyond me. That was really the biggest issue because this whole exercise is about making movies easy for the wife. So, thats resolved but I still have bluray command problems. I guess its because theyre both samsung, I dont know. Seems I can get around most of it by using the manual controls on the unit for power on/off and eject which she'll be fine with.
