I know DVB-S2 cards can do DVB-S that's the reason to force VDR to use DVB-S only cards for DVB-S before the DVB-S2 ones, which if you want a DVB-S2 channels, so is your DVB-S2 cards free.
But one should get a way to tell VDR no to try to tune DVB-S2 channels on DVB-S card.
You can do that. In fact the application should do a DVBFE_GET_INFO. This will query the capability of that specific driver. Based on the driver capabilities, issue a tuning request. That way a tune will be attempted only on the capable device.
It is a simple check, though.
Reinhard,
The patched version doesn't look at the device capability flags, before issuing a tune ? Or is something else wrong/missing ?
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.
How can you ask a DVB-S device to tune to DVB-S2 ? Poor demodulator, it has to do what it is not even capable of. :)
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.
The logic wouldn't be much different. It is the same as requesting a DVB-C device to be tuned to DVB-S. The CI interface doesn't make the hardware look any different.
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.
Ok, I will ask Marco on the relevant. Thanks for the feedback.
