Can someone please help (Dish can't). I bought a used dvr625. Had existing Dish500 ant. w/dual lnb 110/119, sw21 w/one cable coming down into house. Added a Dish separator behind receiver with a feed going to each tuner input. Problem: one tuner gets both sat's no problem, other tuner only gets 119. When I do a "switch test" it checks out fine...?? I replaced sw21, and separator-no fix. It's not the receiver because if I switch around the inputs off the back of the separator, it reverses which tuner has the problem. The separator is labeled "DP", but nothing else in the antenna config is "DP", does this create a conflict? if so, what is the correct separator to use? Any help/suggestions would be greatly appreciated!!!
