said by damink23:Will all new HD channels going forward be mpeg-4? That would seem to make sense.
Any new HD channels in the LOWEST channel tiers (Select and Prime) will likely stay MPEG-2 for the next year or so because of the huge number of 6000 series boxes still in the field. New HD channels added to the highest tiers (Ultimate and Extreme) will likely be MPEG-4 from the beginning.
