    Is there a program or process that I can take a burned DVD that has the audio "Out of sync" and reprocess it to bring it back into sync?

    It can often be corrected.
    Is the sync out by a constant amount?

    If it's constant, you have to find out by how much and you can do that by using a media player like VLC.

    Play the movie and use either 'Ctrl K or Ctrl L' to get the number.
    When you have the correct factor, write it down (it's either positive or negative e.g 500 or -500).

    The movie has to be demuxed into video and audio streams (.m2v and .ac3).
    Use PgcDemux (remember to check the box for the video) and 'Process' to a new folder.

    Run AC3 Delay Corrector, load the AC3 file from PgcDemux and insert the value (positive or negative) from VLC in the 'Start-delay' box.
    'Write' the new AC3 file.

    Run MuxMan and load the video (.m2v) and the new ac3 file (select the language) and 'Start' to create the new DVD.
