I don't get either. We have had SDV for 2 month now, but they have not added the HD channels for some reason.
We are in a big area, which includes about about 8 cities, all hooked up to the same system (Old Comcast).
I talk to a Tech about 2 months ago and they were told then the end of October, talk to him again last week and now they have no date at all. I don't know what's going on with this.
