Maybe. But why should vdr need a plugin to do normal diseqc 1.3
positioning? IMHO it should work 'out of the box'.
I guess this does not mean that there should not be a hook, just that
its use should be optional and only an optimisation for positioners with
plugins that can tell when the dish has finished moving. (actuator, and
perhaps future diseqc positioners...)

I did not really mean that attaching receivers for live tv/transfer mode
should wait. As I said, I think the drivers should 'just work' in this
regard. Setting a filter should not be a problem even if there not
currently a lock. But is this the case for all drivers? Perhaps we
should ask on the linux-dvb list?
Waiting is needed for eit scanning, and perhaps other things, like
recording, teletext etc.

True. I know the problem.
