Thanks. Since I asked this in the first place, let me put it another  way: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.

Ditto.

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,Z.
