My guess is that the problem you have here is that the city.ts file you
use to decode pat/pmt is not actually from the transponder you are
trying out with dvbstream. Because in the decode_pat output above there
is only one channel in the TS.

Note that you can also use VLC to grab only one channel from the TS. to
do this use --programs <program number> --sout file/ts:<output filename>

where program number is the id of the channel you want ( 1 in the above
case). VLC handles all the PAT and PMT parsing for you so you don't need
to mess about with decode_pmt/decode_pat.
