mythtv has started calling grabbers on a per-day basis for up to 21 days.
FIX: Shepherd now lists a 'preferredmethod' in its --capabilities list.
MythTV then calls shepherd with "--preferredmethod" to ask what it
prefers, Shepherd returns 'allatonce', indicating it would prefer to be
called just once.
When it was calling per-day, it was using the syntax:
--days 1 --offset 1 (expecting day one)
--days 1 --offset 2 (expecting day two)
--days 1 --offset 3 (expecting day three)
That is different to our interpretation of the XMLTV spec & grabbers.
It would have worked if instead it used:
--days 1 (day one)
--days 2 --offset 1 (two days but skip day one)
--days 3 --offset 2 (three days but skip day two)
Haven't actually fixed this one, but due to (1) above, mythfilldatabase
just calls us once now anyway.
mythfilldatabase always calls with --quiet.
We don't want to be quiet, so change our --quiet parameter to --reallyquiet
and ignore --quiet for now.
