I have noticed one channel (Oxygen) has it's program guide saying just "24/7 Weather" in four hour blocks. I checked zap2it's listings, and they show the normal programs on it. So now I'm wondering how to fix it... Is there an easy command (ala mythfilldatabase, unfill?) or would it require tinkering in the mysql database to clear it out for a fresh download.

I tried 'mythfilldatabase --refresh-today' but that didn't change it any. The channel number and callsign match up with www.zap2it.com's tv listings. Any ideas?

Newer versions of MythTV let you extract guide data from the channels directly, at least for ATSC - maybe for QAM. Check your channel setup in MythTV and see if you have this option turned on or off. I suppose it's possible that you could be getting bogus guide data from one of the sources.
