Manu,

I can confirm that when I enter a channel manually to my channels.conf 
file I do get a FE_LOCK with szap.

Output from szap:
bash-3.1$ /data2/hg/dvb-apps/util/szap.old/szap -c Astra-19.2E.conf 
"Nederland1"
reading channels from file 'Astra-19.2E.conf'
zapping to 1 'Nederland1':
sat 0, frequency = 12515 MHz H, symbolrate 22000000, vpid = 0x0205, apid 
= 0x0058 sid = 0x0fab
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
set to frequency 1915000status 00 | signal 0000 | snr 0008 | ber 
bfab5b38 | unc 0804c794 |

FE_HAS_LOCK
status 14 | signal 0000 | snr 000f | ber bfab5b38 | unc 0804c794 | 
FE_HAS_LOCK

Content of Astra-19.2E.conf (my channels.conf)
Nederland1:12515:h:0:22000:517:88:4011

Values for this channels were taken from 
http://nl.kingofsat.net/pos-19.2E.php.

In the messages.log file I get the usual which ends with
Dec 29 15:30:40 garfield kernel: mb86a16_set_fe: NO  -- SIGNAL

I did a scan on multiple satellites with transponder lists from 
http://kingofsat.net. I will put up the results in the next couple of days.

Regards,

Michel.
