Okay, pardon my ignorance and if I got the terms off, but... In the past, I thought that QPSK and 8PSK was the method of compressing HD channels, and that Dish was converting over to 8PSK in order to get three HD channels on a transponder instead of two. Now, I read somewhere that the recent receivers receive the SD material in QPSK, but are capable of 8PSK for additional compression without loss of quality. Is this correct? How long has this been true?
