Hi ! 

I run suse linux 9.1 with kernel 2.6.5-7.145 an i have a Skystar2 PCI DVB-S 
card. 

I have the following problem:

I have a DVB-S stream in L-Band (1.241GHz) and i try to tune to it with 
dvbtune. So when i run : 

dvbtune -c 0 -f 1241000 -s 27500 -v 410 -a 420

Using DVB card "Zarlink MT312"
tuning DVB-S to L-Band:0, Pol: Srate=27500000, 22kHz=off
polling....
Getting frontend event
FE_STATUS: FE_TIMEDOUT
Not able to lock to the signal on the given frequency
In order to try with Ku band i get the default LOF from windows which is 9750 
and i calculate the frequency then i run the command :

dvbtune -c 0 -f 10991000 -s 27500 -v 410 -a 420

Using DVB card "Zarlink MT312"
tuning DVB-S to L-Band:0, Pol: Srate=27500000, 22kHz=off
polling....
Getting frontend event
FE_STATUS: FE_TIMEDOUT
Not able to lock to the signal on the given frequency


Finally when i run 

dvbtune -f 10991000 -s 27500 -m 
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()
Signal=0, Verror=0, SNR=65535dB, BlockErrors=0, ()

The signal is good i verified it running windows on my PC ...


I don't know what to do ... any help ??
