[linux-dvb] Streams recognized by dvbnet

[Michael Harpe]

I have been working on debugging reception of a datacast for a while now.

I have determined that the data I am interested in is in PID 0x1af3. Here's
what I get from a dvbsnoop pidscan...

dvbsnoop V1.4.00 -- http://dvbsnoop.sourceforge.net/

The section ID is 0x3F (decimal 63) and as you can see it's ISO/IEC 13818-6
reserved. The data is mostly ASCII text files and I can see them clearly in
dvbsnoop dumps. The data is IP/UDP data. 

Is this why I get no packets from dvbnet? 

Thanks!
