I'm not sure what happened but I would guess that you used the OTA 
xmltvid's to identify the channels. The only way that makes sense is if 
mythfilldatabase queries zap2it for channel/frequency etc. information. 
I did not think that it did that, but it may.
I'd love to be able to say I could look at the code to confirm that, but 
  I don't do C++...
