I must admit, I didn't have a look at the source code so far, but
from what I recall, I don't think that it is that easy. I think,
a simple check will only make VDR tell you that the channel in
question cannot be received.

I've experienced myself that VDR used the DVB-S2 card for a DVB-S
recording and then endlessly tried to switch to a DVB-S2 channel
using the DVB-S card -- obviously without success.

VDR's device selection logic is already quite complex. It has to
deal with FF cards which have so far been used to watch the DVB-S
channels, cards which provide CI interfaces and simple receiver
cards. Moreover it now would have to deal with cards capable of
doing DVB-S2, with or without CI interface respectively.

As I'm only distributing the DVB-S2 part which Marco Schlüßler
provided several months ago, I've contacted him and asked him for
an update.

Bye.
