OS X DVD Player won't play audio from ffmpegX authored DVD

[urchin]

I am trying to author a DVD from elementary video and audio streams (m2v & ac3). I am using OS X 10.2.8 and ffmpegX 0.0.9a. Here's what I've done: I muxed the elementary streams into MPG form, and authored them as a DVD (VIDEO_TS) using ffmpegX.

Here's my problem:

The VIDEO_TS folder that ffmpegX creates can be played using DVD Player v3.2, but there is no sound. I have tested the VOB files independently by playing them on MPlayer OS X 2, and both audio and video work great! Why doesn't Apple's DVD Player play sound from ffmpegX mastered DVDs?

I have included ffmpegX's process output in case it is helpful:

Any suggestions would be greatly appreciated!

PS - I have also tried using Sizzle 0.5 to multiplex these two streams and then author the DVD but the audio and video are out of sync. ffmpegX solved the sync issue.

Strangely, I used Minx Transcoder 1.1b3 on the same elementary streams, and the audio was PERFECTLY synced. Lesson: If Sizzle, or ffmpegX doesn't sync the audio, try Minx Transcoder.
