You have a few options. If you want the ability to sub to channels you need to look to the Motorola DSR922. It is the only digital offering out there for residential usage. Basically just unhook your present receiver and hook it up. Other options would be to use your
classic with a
BSC621 or BSC621-2 lnbf along with a
VBox. The other option would be to replace the classic with a receiver that can control polarity of a standard feedhorn setup combined with a VBox. The VBox gives you the ability to move the dish with a DVB FTA type receiver (not required if you choose the DSR922). I believe the Pansat receivers will control polarity. Not sure on that one you will just have to do a bit of homework.
