So I'm back to my testing and this is the current syntax I'm using for 
streaming EuroNews as a test for MPEG-2 TS source with multi audio.

vlc --color --ttl 2 --ts-es-id-pid --programs 8211 dvb: --dvb-adapter=2 
--dvb-frequency=12597000 --dvb-srate=27500000 --dvb-voltage=13 
--dvb-budget-mode --sout 
'#duplicate{dst=std{access=udp,mux=ts,url=224.0.1.7:3001,name="Euronews"},select="program=8211"}'

Now I would like to select only specific audio IDs, I was expecting to 
use the "es=" command and select all the Video and Audio IDs I wanted my 
  TS to contain, .... ,select="es=2221,2231,2232"}' for video + French + 
English Audio. Unfortunately if I do so I only get the video and no 
audio at all. I suspect I'm doing something wrong so I used the previous 
suggestion and replaced --sout with --sout-all but this didn't seem to 
make things better.

Where am I going from and what did I missunderstand from the streaming 
howto?

TIA
Thomas
