Wow, that's complicated! ;) The recur module doesn't do
compound
schedules; you'd have to combine those three requirements
yourself,
either with nested workers, or with a single worker that
just ignores
invalid datetimes. For example, I'd probably write:

    class MovieWorker(recur.Worker):
        def work(self):
            if (self.nextrun.day not in (5, 6) 
                and (7 < self.nextrun.hour < 17)):
                take_frame()

    mw = MovieWorker("30 minutes")

You could also pass the (5, 6) and (7, 17) bounds as
arguments to the
worker, if you needed that flexibility. Normal Python rules
still apply.

Rob C.'s code gave me a head start, thanks for that Rob,
and the
"first" thing I did was to crash into that wall

.... and then you appear to push me in the right direction.
I'll have
to 'schedule' a bit more Python-time this weekend.

Thanks,

Ingo
