  From watching my backend log - when the system is idle, it tunes to 
each channel in turn and listens.

  If you are watching or recording it can no longer scan and only gets 
the current station's EPG.

  My experience in Sydney is you are better off with out it - the 
stations are inconsistent.
  At one stage ABC-2 was transmitting 'this service is temporarily 
unavailable' and as the EIT scanner received it it replaced the program 
info that had been downloaded from the www with this text. Not very 
usefull. Missed a recording.
  I've found running it for other channels 'dangerous' if you are 
looking for program names - as the EIT data will be different from the 
web data and change the program name or you end up with gaps in your 
program guide...

  It has the potential to work well, but I get the impression our 
broadcasters don't care.
  I'm now using the 'on air guide' only for the HD channels, which I 
don't watch anyway - my output is Composite to an old CRT TV monitor.
