I think it has to do with the way INHD wants to charge DirecTV for the channels. INHD, which is owned by a number of cable companies, if I remember correctly, is charging per digital customer. On cable systems the HD customers are a digital customer. INHD is not charging cable companies for customers who don't have the digital package. On DirecTV 100% of the customers are digital, even though only a small percentage are HD subscribers, so it costs DirecTV a lot more to offer INHD. I believe DirecTV is in the courts now to get this changed so they are only charged for the actual number of HD subscribers and not every subscriber.
