Seawolf, after going thru the video, just to make sure nothing is changed from normal set ups, you clearly Do need to use your Power Inserter.
Here is the easiest way, take the coax from the dish (port C), run coax from there to your PI then out of the PI into the recvr , make sure to use the input on recvr listed SWM, it's usually the 1st one.
No BBC's are required when using a SWM set up.
Also, if your only using 1 recvr, you can skip the splitter and go right from PI to recvr .... IF your doing more than 1 recvr, you'll want to make sure the out from the PI goes to the Power Bypass post, connect your other recvrs to the splitter.
