Right, I meant using a non D*tv branded Actiontec MOCA bridge rather than buying D*tv's DECA. Not for the receivers, but to attach to the LAN. But you can't get a midband unit non-branded so far as I can tell. Nor can I find any interface to flash the generic units--I don't do JTAG header stuff. Plus you'd need a DECA firmware dump. (I assume Actiontec's MOCA box is more or less the same as their industry-abandoned HPNA coax bridges, which I have, and that the DECA is no different.)
Since D*tv outright refused to sell me a DECA w/o a DVR on my account, despite me pitching a fit about being deprived of features I'd have in-box if the local contractor had delivered H24s, I just broke down and bought one from an external supplier. As I had to do to get the miniDIN component out cables. This last go round had be about an inch from canceling my service after many years...D*tv CS is incredibly shortsighted.
So I'll get the bridge installed shortly and we'll see what I can do with it.
