I have downloaded latest hg clone http://linuxtv.org/hg/dvb-apps and replacing szap.c. 

szap compiled successfully.

Also I have installed http://jusst.de/hg/multiproto tree (dvb-core.ko
and another modules). My card (KNC TV STAR DVB-S) detected successfully:
saa7146: found saa7146 @ mem f89a4000 (revision 1, irq 17)
(0x1894,0x0016).
saa7146 (0): dma buffer size 192512
DVB: registering new adapter (KNC TV STAR DVB-S)
adapter failed MAC signature check
encoded MAC from EEPROM was

DVB: registering frontend 1 (ST STV0299 DVB-S)...
budget-av: ci interface initialised.

but "hacked" szap won't work:

szap # ./szap -a 1 "MTV Russia"
reading channels from file '/root/.szap/channels.conf'
zapping to 2 'MTV Russia':
sat 0, frequency = 12245 MHz V, symbolrate 27500000, vpid = 0x0142, apid
= 0x0194 sid = 0x283f
Querying info .. Delivery system=DVB-S
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'
ioctl DVBFE_GET_INFO failed: Operation not supported

As I see DVBFE_GET_INFO is not implemented for stv0299. I have commented
this call in szap (because obtained fe_info is not used inside szap -
seems like a stub call). szap stil not work:

szap # ./szap -a 1 "MTV Russia"
reading channels from file '/root/.szap/channels.conf'
zapping to 2 'MTV Russia':
sat 0, frequency = 12245 MHz V, symbolrate 27500000, vpid = 0x0142, apid

Querying info .. Delivery system=DVB-S
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'

do_tune: API version=3, delivery system = 0

do_tune: Frequency = 1645000, Srate = 27500000

not "hacked" szap lock's successfully:

Please, explain how to solve this problem ?
Thanks !
