Thanks. Since I asked this in the first place, let me put it another  
Currently there is no other way to get DVB-S2 tuning, other than going  
with the multiproto tree, such as a patch-set for the main hg tree?

Is this assumption (also) right?

Thanks again. I tried again with 2.6.22+multiproto+szap2 and I got it  
to work.

I got http://www.free-x.de/vdr/patches/hdtv/szap2.tgz and it seems to  
work fine.

I also tried http://jusst.de/manu/scan.tar.bz2 but could not get it to  
work. I have problems compiling the current dvb-apps tip but that's  
another story. There was a binary in the package but it didn't work  
(scanning failed).

So, to conclude, as Holger Steinhaus noted:

The 2 things that can "speak" to the multiproto drivers a compatible  
version of the DVB API "language" are
- szap2 and
- vdr-1.5.14 + h264 patch ?

Are there any others?

If I use szap2 first, then I can also use dvbstream or dvbsnoop as  
well. I have to keep szap2 running though, because the frontend shuts  
down after some time, despite the dvb-core module option  
dvb_shutdown_timeout=0 (I think I have seen this previously reported).

One last question:
Is there any documentation (such as wiki pages) anywhere for  
multiproto-specific features? For example, I read about the legacy=(0| 
1) option for the cx24116 frontend in the list archives and in  
cx24116.c comments, but I was wondering if such information is kept  
anywhere else?

Thanks again, Igor, Holger, all, for your help.

Best regards,
