I'm a bit of a sports nut, and I have 4 Directv Receivers (2 HD DVR, and 2 HD), and on many occasions I hook all them up in my living room to watch football, basketball, etc. The one thing that drives me crazy is that I have to run coax cable from the walls, out to the living room to get everything to work. I was wondering if there is anything out there yet so I don't have to string that coax cable? I was thinking couldn't there be something that you connect some sort of transmitter from the wall, and have a receiver screwed into the coax port on the Directv Receiver???
