The arguments to mplayer don't quite work for me for the scaling and
cropping, but you can take that bit out. Try this, it works better here:

$ { cat > ripper && chmod +x ripper; } << EOF
#! /bin/sh

rm stream.yuv
mkfifo stream.yuv
rm audiodump.wav
mkfifo audiodump.wav

mplayer dvd://1 -alang ja -ao pcm -vc dummyxy \\
-vo null -cache 8192 >/dev/null 2>&1 &
AUDIO=\$!
kill -STOP \$AUDIO

mplayer -cache 8192 -vo yuv4mpeg -benchmark -nosound \\
-vop expand=480:352:0:0:0,scale=480:288:0:0:40,crop=640:512,pp=lb/dr\\
-spuaa 4 -slang de -spugauss 0.5 -spualign 1 -sws 7 \\
dvd://1 >/dev/null 2>&1 &
VIDEO=\$!
kill -STOP \$VIDEO

{ sleep 2; kill -CONT \$AUDIO; kill -CONT \$VIDEO; } &
~/bin/encoder_example -a 0 -v 4 audiodump.wav stream.yuv > theora.ogg
