AC3 Will Not Play

[Equus]

OK, I'm sure this is user stupidity, but here is my problem. I'm using FFmpegX to burn .mov files (recorded from VHS into iMovie) to DVD on occasions when I need to get around iDVD's 90 minute limit. I am getting decent quality video, but no audio track. I have selected the AC3 Dolby Digital option in Audio because if I select MP2 I have to manually change the settings on my set-top DVD player from bitstream to PCM in order to hear the DVD's audio. I don't want to have to do this; iDVD seems to encode audio just fine with no changes needed for the DVD player to hear them.

When I encode in AC3, the created .vob files play audio in VLC, so I know it's there, but as I said the DVD player won't play audio at all, and neither will Apple's DVD Player play the audio when I tell it to open the Video_TS folder from the created DVD image.

The settings I am using are Audio: AC3, 224kbit/sec, 48000 Hz, I'm using High Bitrate DVD NTSC settings (video rendering is fine), Profile is DVD and "Mux as" is DVD.

Can anyone help? eMac G4 700mhz 512MB RAM Apple Superdrive (DVR-104).

Thanks!

I could never get any AC3 file, produced by ffmpeg, to work very well. Through my own experimentation I found it was able to play in Mplayer, VLC, & PS2 but unable in Apple's dvd player, My Apex, or my Sony set top. Specifically, Apple's dvd player sped the video up to almost double the normal playing speed when ffmpeg's AC3 file was added. To test that this wasn't a video encoding error, I applied an MP2 of the audio to the same video and all was well. Any information on this would be greatly appreciated, as this is an issue that has vexxed me for some time now.
