Forgot to tell that you need to use libmpeg2 from cvs. Version 0.3.1 isn't 
supported.

I did a quick test with an extract from a dvd (copied on my hd).

time ./vlc -vv file.vob vlc:quit --noaudio --dummy-chroma YV12 -V dummy -I 
dummy

with vlc's mpeg2 decoder:
real    1m44.099s
user    0m19.558s
sys     0m0.241s

with libmpeg2:
real    1m43.878s
user    0m26.884s
sys     0m0.295s

Which means the libmpeg2 version is about 1.37 x faster than our custom 
decoder!
