Thanks - changed my settings to:
Use DiSEqC:                no
SLOF (MHz):                12500
Low LNB frequency (MHz):   10750
High LNB frequency (MHz):  11700

and I no longer the the "out of range error" which is progress I guess!!

But I still get these errors and no picture on any channels:

I think I may have a driver problem - not sure if the dm1105 chipset on my 
dvb-s card is well supported in Linux even though scan seems to work fine:
./scan dvb-s/OptusB1-NZ -l 11300 -x 0
scanning dvb-s/OptusB1-NZ
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12456000 H 22500000 9
initial transponder 12483000 H 22500000 9
>>> tune to: 12456:h:0:22500
