Source: 720x480, 16x9, 29.97 (3:2 polldown) MPEG w/ 5.1 AC3 audio

Processed: By DVD Architect Studio. It doesn't support anything but 29.97 fps so it insists on reencoding the video stream.

Action: Using ifoedit to remux the original video stream ("source") into the VOB.

Problem: Audio frequently drops out, almost like skipping, during playback.

Any thoughts?

Thanks.
