I have compiled ffmpeg with lame support and compiled vlc with the following 

-- /configure --enable-dvdread --enable-dvdplay --enable-v4l --enable-mad 
--enable-ffmpeg --enable-alsa --enable-gnome --enable-dvd --enable-dvbpsi 
--enab
le-vcd --enable-faad --enable-xvid--enable-ogg --enable-ncrurses 
--with-faad-tree=/tmp/vlc/faad2/ 
--with-ffmpeg-tree=/tmp/vlc/ffmpeg-cvs-2003-05-16 --with-l
ibmpeg2-tree=/tmp/vlc/mpeg2dec-0.3.2-cvs --with-ffmpeg-mp3lame

but i am unable to output mp3 as audio.
I have the follwing error.

[00000165] stream_out_transcode private debug: creating audio transcoding from 
fcc=`mpga' to fcc=`mp3 '
[00000165] stream_out_transcode private error: cannot find encoder (avcodec)
[00000165] stream_out_transcode private error: cannot create audio chain
[00000170] packetizer_mpegaudio decoder error: cannot add a new stream
the strange thing is that the input was view as "mpga " and in my vls 
configuration file i Have put AudioCompression="mp3". So may be vls doesn't 
have send it as mp3 ?

I don't know how i can resolved this. The goal is that i would like edit the 
jt-rtbf-Aug081060623000.ts  file sended by vls to only get a sequence of the 
file.using a video editing tools but i have not yet found a good way to do 
this. any ideas are welcome .

Thanks,
Philippe.
