I have a family member that works at Mediacom, and she told me that a rep from channel 25 called a couple days ago. It seems they are having a lot of problems, and want medicom's help in going digital. Maybe it has something to do with that.
I have an HD set and have Mediacom. However, it doesn't have a built-in ATSC tuner (its an early Samsung flat screen) and I haven't decided what to do to try to get digital from them or look for an external HD tuner with HDMI inputs.
