That sounds like the LNB settings are wrong. For Sky LNBs offset should
be 11.3GHz fixed. I have LOF switch as "1" and both High/Low as 11.3GHz
(11300000000 since it's in Hz IIRC).

If the LNB settings look correct, then try tuning by hand using dvbtune.
Pass the -f parameter as a _local_ frequency (ie, 950MHz to 2.15GHz)
because dvbtune only understood Universal LNBs when I last checked.
Conversion from the service-ids.txt is subtract 11.3GHz from the
frequency listed there.

If it still doesn't lock, you may have an unusual card with a different
tuner than the driver expects. In that case, driver hacking might be
required. But that case should be very rare. You might also have an odd
LNB (Universal is most likely if it's not a Sky one), or confused
multiswitch, but these are equally unlikely causes.

Hope that helps. If anyone has suggested improvements to the DVB-S stuff
on pvr.geek.nz, please feel free to edit it!
