I've been thinking about getting a Slingbox but I'm curious on how I would hook it up. My HR20, hooked up to my tv via HDMI, is in the Family room. I have a Linksys wireless router connected to cable in a bedroom and the computers are in another room connected to Linksys router via the wireless usb devices. What would be the hook up steps? I won't be able to run anymore wires around the house. This is all new to me. Thanks.
