    I forced the configure with --enable-a52 --enable-mad

    But still don't have these entries... :O(
    How can I force this ? (I have 0 error on building)

$ ./vlc -l | grep a52
VLC media player 0.7.2 Bond
  a52sys                Raw A/52 demuxer
  a52tospdif            audio filter for A/52->S/PDIF encapsulation
  a52                   A/52 parser
  a52                   A/52 audio packetizer

I tried this, but no effect :O(
ffmpeg wall build like this :
./configure --enable-vorbis --enable-a52 --enable-pp --enable-gpl --disable-
ffserver --disable-ffplay
