This is what I presently have: H20-600 H20-100 HR22-100 R15-100 HR21-700 The dish on the roof has 4 wires going to a switch (8 connections out of it) in the attic, with 2 coax each going to the the DVRs and a single coax to the H20-600 and H20-100. I have a broadband router right next to the H20-600. The router is located right under the switch in the attic. If I need to get another cable to it, it will be easy to do. What will be required to get WHDVR? Will any of the receivers need to be replaced? Will the switch in the attic be changed? Will any additional coax be needed? What is covered in the cost of the install and what isn't? Thank you very much!
