Are you saying that the channel is detected, but you can't "manually" match the channel to the xml guide data?
Is this the page your talking about?
The Auto Match doesn't work (at least for me) to match all the channels, there are many that need to be done manually ( the "click here to configure" step).
I have also come across a few channels where there is no epg data to match it to. Foe example I will have a channel 43.1, 43.2, 43.3 where there is no data for 43.1 but the other two subchannels have data. If this is what your seeing, that is a problem with the epg source. You could try a different source.
I'm not sure where the guide data is set to "Auto". Can you explain what step this is in the setup procedure?
Is this the step your referring to?
