DirecTV's love of Starz and Showtime and flipping of the finger to HBO/MAX is very well known. If you need a reference or link you must be new to this site and or DirecTV.
I'll give you an example the other guy didn't mention:
In June of 2007 a press release with a PROMISE of 13 HBO/MAX HD channels for a fall 2007 launch was made by DirecTV. They never delivered on their promise, but we did get a handsome handful of Showtime and Starz Channels in HD.
Another point (already mentioned):
No HBO/MAX On Demand
Another point (already mentioned):
Adding HBO Zone and HBO2 East in HD and no new Max in HD. WTF??? There are 26 available HBO/MAX HD channels and they carry currently 4 of them with 2 more on the way.
Another point (not mentioned):
No HBO Comedy (which is very popular with other providers). No Actionmax, Thrillermax, Outermax, 5starmax, wmax, or @Max. Just the flagship Cinemax and Morrmax.
Do you really need any more proof that DirecTV doesn't care whether we subscribers want HBO/MAX HD or not?
