I'm considering a "whole home solution(DVR) w/internet". Most of my receivers are quite old. I'm assuming my HR23-700 is OK to go as is. What will Directv substitute for my SD DVR(R10)? How about my 2 regular SD's(SD-HBH's)? The R10 is currently on an SD TV but will be on a HD TV before the install. What if I installed my old HR10-250 instead of the R10 on that new HD TV before the install? Does the $99 equipment charge include replacements for all 3 of my older receivers? Will the $49 installation fee also cover "splitting" a 2nd story outside run and then having that 2nd line enter the house again at the 2nd story about 30' away into the upstairs computer room to access my router? Any feedback will be greatly appreciated.
