I had the Dish guy out to do installation yesterday... After going around my house, his recommendation was to "stick with cable"... I was trying to set up 2 receivers, hooked to 2 tv's each... (a 4722 and 2710) Problem is that I have open ceilings in two of the rooms, with no access from above or below... He said the only way that he could see to make it work, would be to wrap the exterior in wire and come through the wall at each tv location... not a very good look on brick... any ideas???
