I am gathering my information to call Directv and have them add whole home DVR and network my Directv for on Demand. I wanted to know and make sure I was asking and receiving the right equipment. Currently I have: HR20-700 HR20-100 HR21-100 H20-100 H10 It appears I have a WNC 4X8 Multiswitch with a 3 LNB Side Car Dish? I have AT&T Uverse modem at 12 Mbps that is beside the HR20 700 and 100 I plan to add one more HD tv to another room so i need another dvr box. Questions: Do i need a new dish? Should I insist on getting a SWiM 16? I assume I need DECA? Will I be able to see my recordings on all of my boxes I currently have? What type of box do i need for the new room I need HD DVR in? About what should my expected costs be?' Should I pay extra $10 to go to 18 Mbps on modem? $20 extra for 24 Mbps? Thanks so much for any help!
