9 DVRs with both tuners active could be run off 1 SWiM-16 & 1 dish. 8 in the SWiM mode and the ninth connected to the legacy ports with full function. The 8 could used DECA and be bridged to your ethernet [with another DECA]. The ninth would be ethernet connected. You could still add another DVR since there are another two legacy ports on the SWiM-16. When you finally exceed 10 DVRs, you next step would be to add another SWiM-16 which can cascade off the first [by using the four legacy ports]. These two SWiM-16s could have their DECA clouds combined into one, as long as the total DECA count doesn't exceed 16, so that means 15 DVRs + one DECA to ethernet.
