I have a prosat 330 receiver and 215 positioner. The system does not work now and I assume it is my receiver. I have a toshiba receiver that I intended to replace it with. However someone told me that a anolog block down system will not work. I understand that there is free to air and premium channels available. This tells me that it might still work. Please enlighten me on if I can change receivers and receive both free and premium channels with my descrambler. Thanks
