Noticed on both my full box and the DTA that there are now channels 1901-1904 labeled "Security Camera". They have nothing on them, of course. The DTA also has a few of the new 1000+ numbers in it, too.
Noticed that little email icon on my cable box was on this morning. First message from Comcast in over a year, as this is the first time I've seen one on this new box (updated for MPEG4). Of course, it was just spam from them about having job openings.
