I have tried both with the s2-liblianin and v4l-dvb versions of the 
drivers and I do not see any differences. scan,szap,szap-s2,scan-s2 and 
vdr-1.6.0 works ok with all of them.

It's just that neither vdr-1.7.0 with your patches or vdr-1.7.2 or 
vdr-1.7.3 without patches are working.

I do not have diseqc in my system and I checked that at least the 
cDvbTuner::SetFrontEnd() method from dvbdevice.c detected that correctly
and went to else part of the block. (=no diseqcs)

When I try to change to a (not previously tuned with szap) dvb-s/s2 
channel, vdr will just notice that the tunerStatus variable in Action() 
method is = 2, which means that "tuned". It will never go to state 3 which 
means "locked".

With szap-s2,szap or vdr-1.6.0 I can however get the locks immediately.
So I am wondering that what could be the most potential places in vdr code 
where I should try to make some changes to tuning/locking code for 
testing. Is it the cDvbTuner::SetFrontEnd method or is there also some 
other methods that are really interfacing with S2API and could affect to 
the tuning or locking?
