Currently have a 5 lnb dish replaced a few months ago. I have an HR20-100 which stays and replacing an old SD DVR with a new hd DVR. The hr20 currently has ethernet to it. I can easily run Ethernet to the other one but I believe I shouldn't need it with deca built in, right? Getting whole home install and cinema connection kit. Since I dont have swm I assume a new dish or would they replace the existing switch with a swim? Then, having Ethernet ready and a gig network, I don't need a wireless kit, but wonder if that is what they would send? I've had my share ef newbie installers - ended up doing most of the wiring while they would put the dish up. So want to make sure they don't just cut corners. Goal here is to be able to stream between the two dvrs... Tia.
