Dish on Demand is just a few movies you have to PAY for, its PPV on demand. They introduced internet on demand where you connect your DTB to your network but that was Pay Per View also. And they were old movies, like 80s movies. I guess its for those that don't have Netflix or live 2 hours from a video store. Geez. You would think they would want to compete with cable but I guess not, its the only thing I miss about cable. But as noted, that's what you have a DVR for.
The 1 cent Cinemax deal for a year I signed up for recently is part of going paperless. You also get about $5 off your bill when you go paperless too. Just call and they will let you know if its still in effect. I signed up in April.
