I'm a long time Dish Network customer but we recently upgraded to the Vip222 and I'm having a problem. For the longest time we've been using two dishes, one dish 500 and one dish 300, feeding 2 SW21 switches. One of the SW21's feeds the upstairs TV and the other feeds the downstairs TV. In the box for the Vip222 comes a seperator prewired with two short coax's to feed tuner1 and 2 from a single line. During the switch test only one tuner recognizes the satallites and when I switch the inputs it also switches the tuner that recognizes. Does anybody know how I can get both tuners to recognize the satallites?
