Ogg-Vorbis audio is not compatible with AVI containers. You must mux it separately.
Extract audio
mplayer dvd://1 -alang en -ao pcm:fast:waveheader:audio.wav -vc null -vo null
Encode audio
oggenc --quality 4.0 -o audio.ogg audio.wav
Use a pipe to streamline the previous two
mkfifo -m600 audio.pipe
These two must be run simultaneously (source first) and cannot be backgrounded.
mplayer dvd://1 -alang en -ao pcm:fast:waveheader:file=audio.pipe -vc null -vo null oggenc --quality 4.0 -o audio2.ogg audio.pipe rm audio.pipe
Calculate target bitrate from movie length and encoded audio size
movie length: 7446 seconds
video_space=$(((700 * 8388608) - $(stat -c '%s' audio.ogg) ))
video_length=7446
video_bitrate=$(( (${video_space} / ${video_length}) / 1024))
