Good Evening! I have a Sanyo tv and a Motorola cable box from Comcast. The #is M10834TCE724. My remote is the one with the grey select button. This remote controls all functions of the cable box except the MY DVR. Can anyone help me? I have reprogrammed, Comcast sent a signal to the box, I unplugged the box and replaced the batteries in my remote. I'm running out of ideas. Any thoughts or advice is very much appreciated. Thank you.
