I finally received all of the items needed to setup my SWM8 and keep my WB68 mutliswitch. Other than having to put a lot of connectors on coax it all went easily. What was most interesting was that I didn't have to do anything on either of my HR21-700s except change the connection to the single cable with no BBC. The SWM8 was automatically recognized and set up with no action required on my part. The reported SWM Firmware version is 18.104.22.168 and SWM Library Version is 2.0.7. Both tuners are working fine and 4 ports are open on the 6X8 multiswich now. Now that I have the extra capactiy I will likely get another DVR unit... or 2... Thanks again for the opportunity to use the SWM8.
