You opened up the LNB housing and started rewiring???

Do you want to see something really scary?
Yes, you can use the DPP Twin. I'm guessing your "201" receivers are actually 301s? Hook one up to the #1 output and the other to the #2 output. The 3rd connector on the R side is an input from another dish and may be ignored.
It's not clear what you have now. Are you getting just one satellite from a DP LNB, or do you have a DP Twin? Either way, do a Check Switch at menu-6-1-1 on both receivers each time you move them.
