Is there a command-line utility for converting a AC3 DVD-Audio stream to 2 channel stereo? I have been able to success encode it in AAC using the info from this thread (http://forum.doom9.org/showthread.php?s=&threadid=75222), but unable to figure out how to downsample it to stereo so I can load it on my iPod.

If you leave the -channels 6 out of your command line it should downmix your audio. And you also could use ffmpeg alone for that I guess.

You can use the usual mplayer command line, I guess:

mplayer -vo null -vc dummy -ao pcm -aofile 2channels.wav dvd://1
