I think however for mixing two sound streams, there might be software that fits better. So I would use mplayer about like ... mplayer dvd:// -vo null -ao pcm:dvd-audio.wav Then I would find a great cli audio tool to mix dvd-audio.wav with the comment.mp3 to produce audio-comment.wav mplayer is then again the right choice to play mplayer dvd:// -audiofile audio-comment.wav That would be my first approach.
