Just hooked one up in early December. The factory splitter box needs to be replaced with a 2x2 box, two inputs, two outputs. After replacing the splitter plug in the blue ray. Purchase a second HDMI cord & run it between the splitter & dish receiver. Now your wired for both blue ray & dish tv. I purchased the new splitter box online for around $35.
