So i just subscribed to directv, the install guy should be here saturday morning for the install, i got a few quick questions. first off this is what i ordered: 1 HD receiver (non-dvr), and 3 SD receivers. Theres a hole from the dish install with 2 coaxs coming through the house into one of the rooms closets which is the "hub" to the wall plates in the other rooms. question...will the installer run new wires for the receivers or use a multi-switch? and if they use a multiswitch do they charge you for that or is it considered part of the free installation? id love for the installer to just use the existing wires and just install a multiswitch but i very much doubt thatd happen considering its free installation.
