How did you try it? e.g. with tcpdump or iptraf? I suppose Satnode uses
Multicasting, so from that moment you tune your card to the right
frequency and pid, you should see multicast-pakets running through your
dvb0_0 device.

Great! Almost every card does that. *SCNR*

Ok, so far everything seems to be correct.

Suggestion: You didn't tell anything about tuning your card to the
desired frequency. So prehaps your card listens to another freq where no
data is transmitted. Are you shure that you are tuned to the right freq?

Try using Dave Chapmans little tool dvbtune. It works perfectly and
brings up the network-interface if involved with the -n option. So you
can forget that network_activator-tool. See www.linuxstb.org for further
details and download. So with that you do
- load the drivers
- tune the card with dvbtune -n <network-pid>
- ifconfig dvb0_0

After that you may see mc-pakets with "tcpdump -ni dvb0_0".

IMHO, those filter settings are correct.

I hope, you'll find some interesting things in my answer. Regards from
