While watching 'The First 48' on CW this afternoon I displayed the quick guide and it was something else showing on it for CW. I recently checked the Titan TV Guide and it has correct shows while Channels is incorrect until 8pm.
Time | Actual | Channels
4pm | The First 48 | ?????? (I don't recall)
5pm | The First 48 | Supergirl
6pm | black-ish | Coroner
6:30pm | black-ish | ..
7pm | Modern Family | Legacies
7:30pm | Modern Family | ..
Hopefully Fancy Bits will find a second guide source to validate accuracy for my zip 06051.
Guide data is provided by Gracenote. You can verify the data at zap2it.com, which is a site using the same guide data.
I actually did confirm what I was watching matched Titan TV and also what is on Titan after 6pm are the same shows that been on CW since this summer. Right now @ 6:26pm my local CW is showing black-ish as in Titan. zap2it just says Local Programming until 8pm. Now that I entered my zip into zap2it it has the same incorrect data as Fancy Bits.
Your guide in Channels DVR could also possibly be mapped to the wrong station id.
Depends on what source you're using for The CW - OTA broadcast, Cable or TVE.
I see two OTA CW channels in the zip you mentioned with different guide info.
20.1 WCCTDT (StationID 32516) and
22.2 WWLPDT2 (StationID 42648)
But then, Gracenote could just be wrong (wouldn't be the first time).
I did end up reporting to zap2it that they were wrong. They responded it should take 2 weeks to correct. I don't know if zap2it is part of Gracenote or just a licensee but they do provide means to contact them.
