I bought an AU9 dish from a garage sale. It was on the house when the couple bought it and they took it down. Can anyone tell me if this is an HD dish? Will it receive the SD signals on Sat 101? (I'm an SD subscriber right now. How would I connect this to a DTV 8 Channel SWM? There are four cables, two black & two white coming out of the satellite and four inputs on the SWM but how do I know which goes where?
