I have decided to use VLC instead of mplayer/mencoder for one single reason : VLC supports MPEG-2 TS muxing (through the libdvbpsi) while mencoder do not.
Of course it may be possible to use this lib with mplayer too, but I don't want loosing my time to hack it ...

Mmm, it seems that it is supported in ffmpeg (and so mencoder) too but it is not documented.
The output format name option is "mpegts".
Alternatively there is apparently the Avidemux software that can do the muxing job.
I cannot test right now ... So it's a note for later ...
