i was able to get one of those DISH PRO PLUS SEPARATOR is that what i need?

SW-21

:( oh ok..... well what if i take the single cable that i have and connect a regular splitter to it and connect the cables to both jacks

I just got the 625, i have 2 dishes connected with a switch (each i think is a 300 dish), so i have only one cable going in into the first tuner jack. the programing works fine and i have all my channels, however i have only one tv so i dont need the dual mode, but when i'm trying to press...
