Good guess. I should have said that I am using a Nova-T card and a PVR-250. > channels are configured in a certain way, the first update could be > populating program information using the uk_rt grabber against > channels which include the DVB channels, and then any DVB channels > which are configured to get their listings from the DVB EPG will be > updated again, resulting in the log entries you are seeing. For starters I didn't know that the DVB had an EPG, which probably didn't help. It would explain a lot. > > 3.

I've can't remember seeing anything related to this in mythtv-setup, just the radio times grabber. I'm now assuming that the radio times et al are *external* data sources but the DVB card provides, what you might call, an *interal* data source. This data is being used by Mythtv despite my ignorance of it so somehow it is setup by default and I need to find a way to restrict it. > > 5.

Sage advice. Until now I thought that this was how it was set up :-( Any suggestions where I might start looking for the configuration side of this internal data source? > Obviously, I have made a few guesses here about your setup, but > without a DVB card I can't see another possible source for the > listings updates you are seeing. Good guesses, and thanks for the very informative response.
