I used w_scan to get the the channels.conf file. I dont have the 
transponder data, so 'scan' is of no use. Unless I extract them from the 
output of w_scan, in which case the to generated files are identical on 
the numbers.

The file varies in size, from around 3MB to around 7MB for the 5 seconds.

I have no idea if the PIDs are the correct ones, but at least they match 
the output from dvbsnoop:

If it can be any help, I have uploaded 2 test files
(both made with "dvbstream -n 5 -qam 64 -gi 16 -cr 5_6 -crlp 5_6 -bw 8
