INHD is one of the DISH offerings coming, the others I will need to research.
Found this:
EchoStar Will Launch New HDTV Satellites (dated May 9,07)
Adelphia used to have the INHD 1/2 channels here. When Comcast took over they dropped them. I was totally PO'd. Would love to drop Comcast and I'm currently reviewing the new AT&T bundle being offered here.
