Hi David,
Thanks for the response, I think you may have hit the nail on the head !

How did you get tzap to do this ? I can't see an option for this !
Can't see a version number in tzap either (downloaded 20th April I
think). Can you post the full output of tzap showing you this config ?
thanks
Can anyone tell me where mythtv stores this dvb tuning information ? I
presume in the database although I'm not sure. I think it may be
highly possible that the config that mythtv is looking at may be
different to that which tzap is using.
