Since you have at least one channel which works it leads me to believe
that iptv plugin is working and the problem could still be in the
transcoding or playback process.
Here's how you can try to investigate a bit more:
Set up a vlc for transcoding in a similar fashion as to how iptv plugin
uses it. For example the following command will do just that for Bahn TV:
vlc
mms://atkon-atkbtvolive-wmv-high.wm.llnwd.net/atkon_atkbtvolive_wmv_high
--sout
"#transcode{vcodec=mp2v,acodec=mpga,vb=2400,ab=192}:standard{access=udp,mux=ts{pid-video=1,pid-audio=2,tsid=3},dst=127.0.0.1:4321}"
--intf dummy
Now open another instance of vlc to play back the transcoded stream:
vlc udp://@:4321
If the stream works perfectly, you can close the playback vlc and try to
play with xine:
xine udp://127.0.0.1:4321
Notice how my examples hardcode the udp port to 4321. If you want to
change it, remember to do so to every command.
If there's no audio on either of the players you are likely to have
something wrong with your vlc installation. If vlc works but xine
doesn't then xine cannot for some reason decode the audio stream.

We try to use pids to make the channels separable from each other.
Overlapping should not be a problem because multiple streams are sent to
different udp ports (and different iptv devices as well). You can of
course modify the script and use different pids if you like.

I think it is the default PMT pid of vlc.
