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

I got http://www.free-x.de/vdr/patches/hdtv/szap2.tgz and it seems to
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
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
Thanks again, Igor, Holger, all, for your help.
