...or lynksis adapter? There is a 3rd way connected directly with an ethernet cable but my hd dvr is in a completely different area and running wires around my house seems too complicated
I would definitely recommend powerline. I'm using some adapters from Plaster Networks that are GREAT! They have some diagnostic tools that allow me to see how fast the powerline network is performing at any point in time, so that I can be sure that I have a good connection.
