I was wondering if anybody has been successful in utilizing the volume "punch-through" feature of the 950 remote. It doesn't seem to work for me. When I try to un-program the punch-thru feature, the LED does not behave as it says it will in the manual, either. I have a Marantz 2000 remote which is proving pretty useless in learning the 950's commands. I read on another thread that it can't learn the source selection button codes from the 950. Oh well....
