For a couple days now. CBS and it's subchannels, actually they had two frequencies, gone on both. PBS gone. CW and all subchannels on that frequency gone. Fox and subchannels have been in and out. Loads of other channels gone. Rescanned, it found some channels but nothing on them, says no signal and no info. Weird, about a week ago some channels seemed to shift within the same frequency. A day or so later they were back to normal, until now. There are no announcements about having to do a rescan like there was last year. I think there are less channels left than what disappeared. I'm going to try hooking up my antenna to my TV to see what I get. I cannot find any info on this, around Chicago I would think there would be some info. I have 4 Tivos setup for OTA, all having the same issue. I HOPE it's not the Tivos, don't see how it could happen on 4, am going to try the antenna connection to the TV now.
