OK, so I have not kept up with the marketplace very much with changes to DVRs, etc, since I got my first HD DVR (HR20?) about 2.5 years ago I think, and I got a second HD DVR (HR21?) just over a year ago for my daughter. So, I want to get two more HD DVRs, and I would like to turn on the whole house networking thing or whatever it is called. I previously had my HR20 networked when it was sitting close to a point on my wired network, but now it is far from a wire. I will have one of the two new units near an Ethernet cable, but the others will not be. One of my existing units uses B-band converters, the newer one does not. Every time I deal with DirecTV I have an ordeal. The first time they came out, the installer was far less qualified than he should have been, and did not know how to deal with my two multiswitches (I am wired for 5 locations, and will be going up to 6 or 7 ultimately). The second time, they installer was doing a new run of cable, clearly indicated to DTV when I ordered, and the installer insisted that I had to pay him an additional $50. I felt I had no choice but to pay, and then never took the time to take it up with DTV afterwards. So, here I am. I'm sure I could figure this out if I searched and searched, and please forgive me for not taking the time, but I have looked before, and I'm just confused. Everyone seems to be worried about getting the latest and greatest -100 or -700 or whatever, and I don't know what I should want in that area, but I do know that I want two more receivers, and I want them to work, and I want them to be networked to each other.... And I don't want there to be issues with my multiswitches (which were originally installed with the 4 DirecTivos I got like 6-7 years ago). For that first HD install, the guy was at my house for over 6 hours.... Per the DTV site, I can get one receiver for $99, and the 2nd is $199. I'm not sure why they cost so much, my first one was free, and my second one was like $49, and I got some sort of service credit to pay for that. So, what do I do, who do I call, and what do I tell them so that I don't get stuck getting the wrong stuff, and the installer not bringing what he needs to do the job? Thanks!
