In the current design it's not valid to have duplicate channums on one
source or multiple sources bound to one card (dvb-s). The channel is
switched in TVRec based on the channum. It would be saner to use the
chanid but I can't think of valid cases to have more than one channel
per source on one channum.

Yes, the channel scanner uses the service id as channum. Given the above
problem we should check for duplicates.

No, it scans only multiplexes with at least one channel with activated
