I have a rather large mpeg-4 in an avi container (mp3 audio) that I'm trying to convert to dvd.

The video plays fine in QT. I'm using the DVD ffmpeg preset. I've tried several times. The video will convert fine, but the audio does not. The resulting mpg file does not have audio at all. The ac3 file ffmpegx creates is invalid and will not import correctly in DVDSP or Toast.

Is there something I could try to get this converted.
