Can't you just ignore that invitation and move on to the next step?

I suppose there will be some differences with DVB-S or the drivers, but 
using DVB-T I never scan until I get to the Channel Editor pages. 
Unless I have reason to believe that the mux/transport parameters have 
changed I just check there that the listed Transports look ok, delete 
all the channels for the appropriate 'input connection' and scan for 
channels; usually just 'on all known transports.'  For DVB-T UK the 
separate muxes are coordinated and it makes sense to tick the 'look for 
linked Transports' box, but that may not work for you.
