i have a dvd player and a vhs player and i have a coax run to 3 tv sets. the vhs works fine, but i can only get 1 tv set to work on dvd by running a video and left and right audio. i have tried to run out of dvd to vhs in and out to a input on another box input and then on the out to the other sets, this still does not work. the only way i see to make this happen is to run a, video and left right audio from each tv to a junction box then out of dvd to the box. any other suggestions. Thanks! the phonedude!
