So I have an older VIP211 and it has the seperator used for both SAT inputs on the back. My setup has recently changed and I no longer need the SD feed back upstream for other TV's in the house....so my question is do I really need to keep the seperator in the loop to feed both SAT inputs on the box, or is that only needed for the setup where you would want to backfeed? Can I simply connect the incoming satellite coax from the dish right into SAT1 input on the box and be done with it and still get all my HD channels?
