All of my hbo channels were HD up until a month or so ago. The sd ones were 300- 312 and the hd ones were in the 1800s. I have limited basic with hbo . I'm probably going to cancel and just get sling. This is nuts.
It's always been comcast. They are the only option where I am besides satellite. My parents have optimum and most of the movie channels are in HD except for some of the showtime channels.
Amazing never knew Comcast offered All HD channels. Have you contactec
Customer Loyalty the dept you say cancel on phone tree? For a reply? They should if anybody would.
