Just installed a Motorola DCX 3400 given to me by Comcast. The CBL 0476 code added onto my One for All URC 9910 got almost all the functions, except for the Day +/-, DVR, and On Demand buttons. And IR learning was a bust on those.
However, the KM file referenced above works like a charm. All the seemingly impossible to learn codes worked quite well. So, thanks (several months after the thread ended).
