Why not still offer the primary SD channels at a reduced PQ. Convert Mate, Gem & One to SD and with the extra bandwidth gained from this launch a new 1920x1080 MPEG4 version of the primary channels as a premium product for the more discerning viewers. This way those with SD only boxes gain the current HD channels now converted to SD while those that want HD and are prepared to invest in MPEG4 gear will finally be able to watch the primary channels in great HD. I will be keen to read what the more learned members of this forum think the technical and regulatory issues of implementing this plan would be.
