As of the final agreement at the end of Dec, only the STARZ channel, and a couple of Encores, were to stay in the listing, but all of the programming is supposed to available on On Demand. Still no app access, though.
I'm with you. I prefer to have all of the channels and browse what is on instead of searching through On Demand (and I have missed the app for years since I prefer to use my Apple TV over the cable box for that).
Right now, it is actually cheaper to drop STARZ on Comcast and subscribe directly with STARZ, but then there would be no channels, only programming on the various apps.
