Now vlc can read a TS with multiple programs and streams them as
 indepandant output (well you need the new TS demuxer so ...)
 (It is not well tested)

 Example: (lines are wrapped)
 ./vlc -I rc --sout-all /ts2:/home/fenrir/test.ts \
    --sout '#duplicate{dst="std{access=udp,mux=ts,url=239.255.13.13}", \
                       select="program=8501",\
                       dst="std{access=udp,mux=ts,url=239.255.13.14}", \
                       select="program=8506"}'
