I have Directv setup with the slimline dish. I have four individual lines going into 2 different rooms in the house. I have 2 of those lines going to my home theater. I want to have HD PIP and my tv will handle that. I just need to rearrange my setup. I want to change the lnb to a swm-5. I have 2 HR21's. I want to run both HR21's off one line. I have plans for the other line. I know this is long, I'm sorry. I just want to double check, that I just need to switch out the lnb, drop bbc's, add power inserter, add swm splitter and re-boot hr21's one at a time and I should be good. I ran my old Directv system and this is just rewiring and changing the lnb on a stationary dish, so that is not a problem for me. I just want to make sure that I have it correctly.
