Is this desynchrony due poor muxing/encoding on the part of the original 
encoder?

Is there demultiplex software that can "fix" the streams to be in sync? 
(if that makes sense)

I'm transcoding high bitrate, high res. (1280x720) MPEG2 video to DVD 
compliant MPEG2 video.  The source contains PCM audio and I'm 
transcoding to AC3 audio.

I hope I'm not sounding dense. I'd like the understand the problem and 
learn if there is a solution to this, since several DVD authoring 
programs only readily accept separate audio and video files.
