I believe you've uncovered a real problem here. I actually didn't think
of the case that another recording would tune away the device that has been
just set to listen to the VPS recording's transponder.
I'll see how this can be fixed in the next version.
I know, that video recorders (at least some) scan all channels, which
are programmed for a vps recording. I assume, because sometimes
xmissions start earlier than announced. But of course they don't
evaluate the information about earlier or later xmission in the epg.
Will vdr see such an announcement and evaluate it?
