I have the HR34 with the 5 tuners and 4 HD DVRs (HR20, HR21, and 2 HR23s). That is thirteen tuners total but if the SWM only sends one wire to the 5 tuners on the HR34 and the 2 tuners on the existng HD DVRs (I assume there is a splitter of some sort so each tuner input gets a wire on the existing DVRs) why does it not just use 5 ports on the SWM which would let me get by with a SWM 8 instead of a SWM 16? Also, with SWM I assume my DVRs will not automatically hunt an available tuner on one of my other HD DVRs somewhere in the house if I were to try to set 3 things to record at the DVR in the den for instance? If it would work that waay i would not need the HR34 but I don't think it works that way, right? Thank you.
