Yes, possibly translator xmltvids.  It is an "artifact" of the
way gracenote does things.

Yes, one would have to run multiple times a day
via cron (or equivalent), mythfilldatabase just runs
(about) once a day.

While everyone has different needs, good scheduling
requires knowing as far ahead as possible.  Having
20ish days is typically goodness.

The grabbers try to only download changes, so the loads
on Schedules Direct are generally minimal no matter.
The grabber must still produce, and mythfilldatabase
must still parse all the scheduled data, but only changes
to the schedules/programs result in database updates
which tend to be the things that really slow things down
when your database is the limiting factor.

And (as Robert points out), the first run(s) can take
longer than following ones, so do not make judgements
based on that first (when you are watching) runs.
And (for that matter) do not make a judgement about
the time when running it immediately again (since
it has far far less to change).  Look instead at the
logs from a nightly run.
