oh i understand that its only HD channels,, but i mean one days Bell will come down to the need to convert 8PSK on 91 so i was just inquiring if the 3100,4100,5x00 are all 8PSK compatible?? But i would figure if the 6000 wasnt, then the 2x00, 3x00 and 4x00 with exception to the 4100 wouldnt be 8PSK???
