Bottom line, I do think it would be smart to get rid of the West Coast Feeds for Cinemax, HBO, Showtime, Starz etc especially as they could all be covered by on demand channels - and it should free up enough QAM space for more HD.
For example, I would not sub to Cinemax now - but get rid of the West Coast Feeds and put on Cinemax HD and I certainly would sub. I am sure there are others in the same boat I am in.
As you need a digital stb for Cinemax anyway, most of the material could be seen On Demand.
