Hi,

this is possible since version 1.1.0. If you only have one LNB, you can use the
global options 

       dvbDefaultDiseqcNr            : default is 0
       dvbDefaultLnbLsof             : default is 11700
       dvbDefaultLnbFreqLow          : default is 9750
       dvbDefaultLnbFreqHigh         : default is 10600

to change the LNB settings. For Diseqc setup please read the
transponders.dcl.diseqc file for the Diseqc satellite definition, which includes
LNB settings for each satellite. To reference a channel of a certain satellite
the satellite identifier has to be added for each entry of the
'define_available_channels' list, but this is done automatically by dtv_scan if
you have defined a Diseqc setup.

Regards,

Rolf
