That would depend on how your cable box audio is routed to the MRD.
I can't find a clear readout on its audio INPUT capabilities. If it does have a digital audio input you could probably run the cable box's digital audio output to it and you'll have surround. If it doesn't have a digital audio input you're limited to stereo audio from external sources. Then I would ask, what were they thinking when the didn't spec a digital input on a multichannel system?
