If you're entering your Latitude, and Longitude, it is probable that you're using USALS, to drive your motor, I have to use V=Box II as I have 4 electrical type wires, running from my motor, to V-Box II. My parents setup was easier, as I used a Fracarro Penta 85cm dish, and basic Technomate motor, so that a co-ax cable ran, from the LNB, to the motor, then from the motor to their receiver. Even then I used Diseqc 1.2, to align the dish, as they only required 3 satellites, 28.2E, 23.5E and 19.2E, which provides everything they want.
Please post back, when you get your new receiver, and hopefully provide a review, for other members.
