I'm considering getting new service with Direct. I only use 3 tv's but have two more that will be used ocassionally, I'm not worried about HD so I want to back feed these two tv's thru coax from the genie and a client. Do they make a "dongle" to do this and would it be a "10 pin to coax dongle" or "componant to coax dongle". I looked on Solid Signal and couldn't find anything.
