If i have a dual LNB, and the 2 lines from the LNB going into the input of the multiswitch with a 4 way output,outside the house, and i have a dvr in the master bedroom upstairs, is there a way from single line of the output of the multiswitch going to the bedroom with the dvr can i put a 1 into 2 mini miltiswitch in the attic for the 2 tuners of the dvr in the master bedroom, if there is such a thing, what i am getting at is to avoid having to run another line in the attic upstairs to the master bedroom from the multiswitch outside, and putting the switch in the attic instead??? it would save a great deal of time. Thanks Mark
