Quite likely the SI data on Hotbird is inconsistent, e.g. the NITs
sent on different transponders contain differernt NIDs for the
same multiplex. However, I don't have time to look into this, and
I don't even have SAT receiption...
dvbscan should take the NID only from the NIT entry for the
transponder it is currently tuned to (check parse_nit()).
