Now I have another question, however, as I move also in the direction of 5.1 to accompany my vastly upgraded family room. The digital cable box I presently lease from COMCAST does not have either the coax or optical audio output. I assume this means that unless COMCAST is so kind as to install a new box for me, I am not getting a 5.1-ready audio signal to my receiver, correct?The literal answer to your question is yes, but it shouldn't matter, unless Comcast does things differently than most. Your existing cable box will most probably be replaced by a new one that includes HD decoding. AFAIK, all such boxes on the market today offer a digital audio output.
If it does turn out that Comcast is providing a separate HD decoder, I'm sure that decoder will have its own digital output. DD is the standard sound format for HD; an HD decoder without a digital output wouldn't be a true HD decoder.
