dvd player and direct tv
I have a bar with four plasma tv's. Each has it's own direct tv HD box. These are all located in a back room. I wanted to connect a dvd player that could send the same signal to all four tv's through the direct tv player. There are two coaxial inputs on the back of the direct tv box. Only one is being used by the dish on each box. I bought a box to change the output of the dvd from video to coax and then split the coax four ways and connected it to each direct tv box.
Now, I can't tune in the dvd player on any of the tv's. I don't know how to get direct tv to switch to this input.
Any help out there??
