The check whether the epg.data file shall be saved (amoung other things)
is done whenever none of the above conditions is true. See vdr.c:

         if (!Interact && ((!cRecordControls::Active() && !cCutter::Active() && (!Interface->HasSVDRPConnection() || UserShutdown)) || ForceShutdown)) {
            time_t Now = time(NULL);
            if (Now - LastActivity > ACTIVITYTIMEOUT) {
               ...
               cSchedules::Cleanup();
               ...
               }
            }

and

   if (epgDataFileName && now - lastDump > 600) {

in epg.c.

So effectively the check is done every ten minutes, but may be postponed
a short while if one of the conditions ist true. Of course, if such a
condition is true for too long in one piece, egp.data may be saved much
later - if at all.
