This must be part of the 'better quality pictures' we were promised by the
BBC :)

I understand the idea of Reed-Solomon error correction, but does the move
from FEC_2_3 to FEC_3_4 mean that more of the bandwidth is taken up with
error-correction data instead of actual audio/video?

Also, can someone explain what the QAM setting means and how it relates to
picture quality / data rate?

Cheers,
Gavin.
