OK I think some took me out of context. I was maning the main stream channels. Voom at least to me was mostly a novelty, very specialized channles that are heavy in repeats.
Most Voom channels (Rush, Rave, Ultra) repeat less than Food Network or HDTV HD. Rave is no less specialized than MHD. Golf would be the most specialized HD channel of the bunch. (It would be NFL Network if they actually had much HD content other than replaying games from Fox/ESPN/CBS.)
D* will overtake E* likely for awhile until E* gets another bird online. E* users have been watching dozens of HD channels for many months, while D* and cable users had to wait. If cable gets rid of its analog band and starts moving to switched digital video, things could get interesting very quickly.
