Are you saying that the different networks don't link to each other? Now that
is just plain stupid, and breaks the idea of the Network Information Tables.
The NIT comes in two versions, one witch should describe the current network
and another wich should describe other networks.
Please make a dump of those tables by:
- Download and install a copy of this tool; http://dvbsnoop.sourceforge.net/.
- for each transponder:
- tzap to the transponder
- dvbsnoop 0x10 -f 0x40 -m 0xff -n 1 >> outfile
- dvbsnoop 0x10 -f 0x41 -m 0xff -n 1 >> outfile
- pack up the output and send it to me (and Tylor?)
dvbsnoop will wait forever if the tables is not transmitted, so wait about 30s
- 1 min, and if nothing happens, just cancel it.
Now amongst those that is really broken is Viasat 5w, because they transmit a
NIT table on 0x40 (actual network), which contains transponders on 13e/19e.
So just be aware of this fact when this scanning program is implemented.
I have attached the output from dvbsnoop on viasat 5w table 0x40.
