I've been doing research on this and am still a bit confused because I get different answers from the techs at DTV. I have 7 HD DVR's. I want to buy an SWM16, like this one here: http://www.ebay.com/itm/DIRECTV-SWM16-SWM-16-Multiswitch-Power-Inserter-With-2-8-Way-Splitters-/281134982207 I would like to run only one wire to each DVR. One person I spoke to said I needed splitters and one said I didn't. I will be needing 14 tuners working from the SWM. Do I need splitters for that? The way I was told to install was to run a cable from the SWM switch to the Power Inserter, plugged into the SWM port on the PI. Then I was confused. I believe she said to run something from the port that comes into my house but my current multiswitch is in the house and I don't have a port installed in the wall that runs outside to the dish. If someone could direct me to an installation diagram that you know of, that would tell me how to plug it properly to get it to work. I looked at the one in here but I didn't quite get it. What plugs from where to where from where? Thanks for any help. Also if you know of someplace else to buy the parts I need for less, please let me know.
