Do you ever see any other "Table XX loaded messages?".
Can you scan this transport properly with other tools?
What DVB is this (S/C/T?).  If it's S is this a transport that has a NIT
present?

If its filling in entries in the NIT (see dvb_transport in the db) table there
could be errors in what the  service sends for other transponders and its
attempting to tune to something that doesn't exist, or the parameters are
wrong.

I have considered this, but it might just read from the same format of files
that scan (with dvb-apps) uses. (This way someone else can maintain these files
instead of it having to be constantly updated as services change).

If you are using a DiSEqC 1.3 motor you need to set this (you hve to change your
earth location in dvbdiseqc.cpp right now), otherwise just leave it alone.. I am
going to make this hidden in the future unless you are using a diseqc motor..

OK I'll take a look..
