Hi.  I've got a new dm1105 dvb-s card which I can't get to work.  I can scan 
and get transponders etc, but can't tune or get a front end lock.

I see there's been some work on this - does anyone have one of these dvb-s 
cards working?

I've just pulled the latest from 
http://mercurial.intuxication.org/hg/s2-liplianin

I can scan and get info:
./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
>>> tune to: 12456:h:0:22500
DVB-S IF freq is 1156000
<snip>

<snip>
C4:12456:h:0:22500:513:651:1921

But I can't get a lock on szap:
./szap -c channels-conf/dvb-s/OptusD1E160 C4
reading channels from file 'channels-conf/dvb-s/OptusD1E160'
zapping to 2 'C4':
sat 0, frequency = 12456 MHz H, symbolrate 22500000, vpid = 0x0201, apid = 
0x028b sid = 0x0781
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Or in VDR -

channel 1, tp 112456
Sep 23 13:50:06 localhost vdr: [2105] frontend 0/0 timed out while tuning to 
channel 16, tp 112483

Although dvbtune says:
./dvbtune -f 1245600 -s 22500 -p h -m -tone 0 -x
