3x4 multi switch

[Vader14]

I have a tri lnb dish with the mutliswitch on the dish. I have the four cables coming into my home. I have two cables going to the DVR and the two other cables hooked up to two other boxes. I want to add another DVR in another room. Can I use a 3x4 multiswitch to two of the lines coming into my house to add the additional DVR? I bought a 3x4 multiswitch but have not opened it since it was $80. I see there are inputs for a 13v and a 18v cable. Can I just use any two cables?

No, you cannot add another multiswitch to either of those two cables because they already come from the multiswitch in the dish.
