Some more info: apparently the problem only happens if a DVB-S2 card (a TT-budget S2 3200 in my case) is (attempted to be) tuned to a DVB-S2 channel after the driver has been freshly loaded. Once the card has been tuned to a DVB-S channel, subsequent tuning to DVB-S2 channels works fine.That scenario works fine with scan-s2 utility.
I just wanted to download the dvb-apps from linuxtv.org, but apparently all those repositories are gone, http://linuxtv.org/hg/dvb-apps is empty.
Any idea where to get the scan-s2 source now?
When I run scan-s2 with an initial tuning file that contains only a DVB-S2 transponder (Astra 19.2E)
S 11362000 H 22000000 2/3
and change scan.c so that it first tunes to DVB-S2, as in
/* set up list of delivery systems*/ //fe_delivery_system_t delset[]={SYS_DVBS,SYS_DVBS2}; fe_delivery_system_t delset[]={SYS_DVBS2,SYS_DVBS};
I get this with a freshly loaded driver:

So apparently not even scan-s2 is able to tune directly to a DVB-S2 transponder without first tuning to a DVB-S transponder.
Can anybody else confirm this, or am I doing something wrong?
