This sounds excellent, if I can turn to Vorbis for audio! =)

Making the video:

i=1
for j in /dev/null video.avi; do
        cat *.VOB | mencoder \
        -sws 2 \
        -ovc lavc -lavcopts vcodec=mpeg4:vhq:v4mv:trell:vbitrate=700:vpass=$i \
        -vop scale=496:288,crop=702:572:10:2 \
        -aspect 16/9 \
        -nosound \
        -o $j -
i=2
done


Making the audio (I wish this step could be optimized using pipes and
stdin/stout!):

cat *.VOB > full.mpg
mplayer full.mpg -aid 128 -ao pcm -aofile audio.wav
oggenc -q 5 audio.ogg


Merging:

ogmmerge -o final.ogm video.avi audio.ogg
