Was as D* subscriber from 2001 to 2016 when it, frankly, just got too expensive. Well the wife wants D* back to get Sunday ticket but I want 4k. I have a total of 5 UDH sets, but only need 4k on at 3 locations. From what I have read, two C61 clients is what I want & my 3rd 4k set is an RVUE device. Will that set serve as a 4k client or does it need the actual box? As far as total equipment, I think I will need the HS17, the aforementioned C61's & an HR54. Does this sound right?
