Chris I'm assuming that's the tzap for BBC ONE?

If it is it's comforting to see you getting a clean lock.

The next stage is to get a clean channels.conf.

If you look at the format of your uk-WinterHill file it should have
either 5 or 6 muxes in the format...

T 754167000 8Mhz 3/4 NONE QAM16 2k 1/32 NONE

If you look in the channels.conf you created using scan you should see
the same date in a different format, together with the channel info.

Can you confirm the uk-WinterHill data you have is up to date as
compared to the channels.conf you created yourself.
