Wait a second now... iDVD doesn't encode from the "TS" folders, it CREATES them, so how did you actually do this -- step-by-step? Did you encode the audio into AC3 with A.Pack then "Add" that to your iMovie project's referencing movie with QuickTime Player? And if you have A.Pack, you probably have DVD SP, so what's the point of using iDVD anyway? Maybe I'm dense, but what you're describing doesn't sound possible with iDVD, unless maybe there are some hacks you're performing on the iDVD project file? Can you just stick an AC3 audio file in the AUDIO_TS folder of a DVD and have it be recognized as an audio track for the DVD? I thought there was more to it than that... Can you enlighten me (us)? - Mark On 3/19/04 12:00 PM, R B Williams at brucewll at comcast.net wrote: > You can.
