This scenario is possible if you are running >1 card using separate listings grabbers - e.g. for the UK, you could be using a PVR-xx0 card with the uk_rt XMLTV grabber, and a DVB card using the DVB EPG. If you 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. > 2.

It is more likely the data being retrieved is correct, but the configuration of the grabbers/mythfilldatabase/channels is causing this behaviour > 5. How do I stop it? Assuming that the behaviour is caused by having 2 sources of listings data running, I would ensure that only DVB channels for which there are no listings available from the uk_rt grabber are set to use the EPG, and all other channels use a common source. This should not only stop data being overwritten, but also aid the scheduler tremendously by ensuring that channels available on multiple input sources have the same listings information. (Imagine if you have ITV1 available on your PVR's tuner, PVR's direct cable input from an external Sky/NTL box, _and_ on a DVB card. If the listings information for the channel differs on the three sources, there is a very high chance that a program's listing information will have different description/subtitle etc which will wreak havoc with the scheduler.) 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.
