Hi

My dvb-s LNB is a Ku-Band LNBG DKF-2024.

The box says:
Input 11.70-12.50 Ghz
L.O. 10.75 Ghz
Noise 0.6dB
Gain 60dB

If I set VDR up as follows:
Use DiSEqC:                no
SLOF (MHz):                10750
Low LNB frequency (MHz):   11700
High LNB frequency (MHz):  12500

When I change channels I get:
Sep 25 21:15:18 localhost vdr: [2058] ERROR: frontend 0/0: Invalid argument
Sep 25 21:15:18 localhost kernel: DVB: adapter 0 frontend 0 frequency 
12456000 out of range (950000..2150000)

If I set it to
Use DiSEqC:                no
SLOF (MHz):                11300
Low LNB frequency (MHz):   11300
High LNB frequency (MHz):  11300

I don't get this error, but get:
Sep 25 21:15:57 localhost vdr: [2058] frontend 0/0 timed out while tuning to 
channel 3, tp 112456
Sep 25 21:17:02 localhost vdr: [2058] frontend 0/0 timed out while tuning to 
channel 3, tp 112456
Sep 25 21:18:07 localhost vdr: [2058] frontend 0/0 timed out while tuning to 
channel 3, tp 112456

I'm using a dm1105 dvb-s card which works under Windows on the same box, but 
szap and VDR do not.  I can scan channels though with:
./scan dvb-s/OptusB1-NZ -l 11300 -x 0

OptusB1-NZ being:
S 12456000 H 22500000 AUTO
S 12483000 H 22500000 AUTO


Any suggestions?
