Thats one reason why I went from DTV (after being their customer for seven years!) to Dish about two years ago. Directv also don't have, Starz Family, Starz Cinemma, Cinemax 5-star and Action-Max, TMC Xtra, and one Showtime channel. You should have checked out what DTV offered before you switched. Before I switched two years ago, I e-mailed DTV on a regular basis, listing these and other channels that I wanted to be able to get, with no response! From the time I switched to about a month ago, they never added any locals, movie channels, etc. (They did add Nicktoons a couple of months ago!)
Good Luck getting them to add any movie channels!
