I have DirectTV. How do I connect a second TV to the same receiver? There are two lines
Coming in from the dish, apparently one is for sound, and one is video? All I want to do is watch the same program on two different TV's. Darn grandkids are never around when I need 'em. Thanks...

From the line out add a splitter (about 5 dollars at Radio Shack) and then run the coax cable from one leg of the splitter to TV1 and the other leg to TV2. The two input lines on your receiver are for two LNB inputs so you can watch one channel and probably record on another channel if it is a DVR
