Well, AFAIKT, nowadays, almost all scanners need just one frequency for
satellite and cable to get all channels (and even for some DVB-T/T2
broadcasters, but this is a way more commonly found on DVB-S/S2/C).

If the extra transponders are listed via other NIT tables (it depends on
the broadcaster), an extra parameter is needed (-N, in the case of
dvbv5-scan), as the scan time per channel increases a lot if it has to
wait to receive all NIT tables. So, most scanners default to use just
the main NIT table, providing an option to parse the other ones.


Thanks,
