Well, it's gotta be _somewhere_ ;-)

Hmm, it's the EPG setup menu, and there's a command button that says
"Scan"... What might that scan? The transponders? The channels?
The user's iris? The bar code on your forehead?
Surely it can't mean that it scans the EPG - because then it wouldn't
be in the EPG setup menu - or would it?

How about taking a look at the MANUAL file?

* Parameters in the "Setup" menu
   Scan                   The "Red" button in the "Setup/EPG" menu can be used to
                          force an EPG scan on a single DVB card system. If pressed,
                          and the primary DVB device is currently not recording or
                          replaying, it will loop through the transponders once and
                          then switch back to the original channel. Any user activity
                          during the EPG scan will also stop the scan and bring back
                          the original channel.

This function is mainly for single card systems.
In multiple card systems the EPG scan is always active when
there has been no user activity for some 60 seconds. The "Scan"
button then simply cuts that timeout short. There is no need for
an explicit message because the primary card is not switched
to a different channel.
