Incorrect. The starting digit of chanid depends on the sourceid of the
video source the channel belongs to. It seems that the value of
sourceid is multiplied by 1000, and then the value of channum is
added. During scanning in mythtv-setup, channel numbers (channum) can
be obtained from either the serviceid of the channel (currently for
DVB-S which can result in very large values of channum) or from the
FreeView EPG channel number (which gives more reasonable channel
numbering) for DVB-T.

I'm quite sure the OP was reporting the value of channum (not chanid)
which was set from a DVB-S scan. The serviceid of BBC2 England
broadcast on DVB-S is 6302.

If what I say above is correct, choosing "Delete all video sources" is
what will help to reset the _chanid_ numbering, but likely not have
any bearing on the channel numbers (channum) seen on the OSD and in
the EPG if using DVB-T or DVB-S.

Also remember that chanid must be unique for each entry in the channel
table. Channel number does not have this restriction.
