And so for 7 HD DVRs that means I have 14 tuners which means SWIM16 and one 8 way splitter and only 1 cable from the 8 way splitter to each HD DVR which will supply 2 tuners each. Correct? Or do I need 2 8 way splitters because even though there are only 7 total cables out from the spliiter? Also, each HR20 needs another 2 way splitter for the connections between DCEA and Sat 1 and 2. Is the setup for HR20-700 the same as for HR20-100?
