Oops, sorry I didn't notice this new patch at all. Is this meant to be 
used with or without my initial patch?

Hmm, too complicated for me to understand right now...

BTW, with my original patch, the channel switching in DVB-T seems to be 
faster. When switching multiplex, VDR also switches to second device. 
When I switch back to the previous multiplex, I believe the first card 
(which VDR changes back to) is still tuned to that and retuning is not 
necessary. However this same thing is the problem also, as Thomas said, 
because you need always an extra free card for multiplex switching 
(which is not a problem for me, because number of multiplexes = number 
of cards).
