My new MX-980 is controlling both Motorola DCH3416 HD-DVR's I have. 1 HD-DVR is downstairs with the MX-980 and the other HD-DVR is upstairs with a remote extender to the bedroom. Anyway of disabling the RF output for a specific device or completely disabling it? Or, is there anyway of changing the "cable" button on the DVR to an "aux" button like on some DirecTV receivers? Please help!! I'm still using 2 remotes to watch TV!!!!!
