I trying to use DVBSnoop on a amlogic device.

I install it on my s905 device and it worked first time. The output I am getting now is not what I got first time round. I could read nit and get EPG data displayed first time I tried.

My question is, is the data sent down through DVB-C encrypted that DVBSnoop can't read?

When I run
HTML Code:
dvbsnoop -s feinfo
I can see my tuner there, with min max frequency but no minimum max symbol rate.

I try to run this command and it just don't do anything

HTML Code:
dvbsnoop -s sec -tn -ph 2 -pd 4 -f 0x40 -m 0xFF -n 500 0x10
It's part of the original autobouquet by lraizer.

What can I do to debug? I'll post all my outputs later
