I'm not quite shure if it is correct to put this in two separate steps.
I'd use ./dvbtune -f 11473000 - v -s 33300 -n <multicast- or unicast-pid>

Yes, I also get Signal Strength: 0, because dvbtune does not read the
correct registers on the nova cards. So more important are the
FE_STATUS-Codes. These above look perfect.

Is the Satnode-Service a unicasting one? Sorry, I don't know much about
Satnode and I supposed it was Multicast.
So with Unicast, you can not see pakets coming through your dvb-card
unless you create the traffic yourself. Give the unicast pid over to
dvbtune behind "-n" and AFAIK you should be all set. Try to create some
traffic over the proxy and look into your dvb0_0 with iptraf or tcpdump.

the .dvbrc is not used by dvbtune.

I know your feelings. I've been in the same position some months before
with a new service in Germany. Good Luck.
