Xvid Audio Sync error while converting to DVD

    Hi there, I have downloaded a series of XVid files (24 x 350mb AVI
    episodes) and was hoping to put 5 episodes per DVD.

    Easy, I thought, using Nero Vision Express, I burn all my projects as
    an image file first, to ensure it is satisfactory before burning to
    DVD. I noticed that there was major Audio Sync errors when completed.

    I have tried many methods to overcome this:

    1. Turn on High Encoding on Vision Express,
    2. Selecting Stereo on Vision Express
    3. Using Windows Movie Maker to convert files to WMV first (after
    converting, the files are out of sync)
    4. Updating the K-Lite Codec Pack to the latest media pack.
    5. Tried AutoGordianKnot as suggested by other users to re-code them to
    xvid, Also installed just xvid codecs and Lamemp3 codec. Still have the
    Audio Sync Error.
    6. Tried Audio Decompressor, which improved the problem but still no
    good.

    Come on guys, I know you can help me on this one. Someone suggested to
    use Virtualdub but I am unsure how to use this, Could anyone spare a
    few mins to describe how to use this?

    Could anyone make a suggestion?

    Anyone know how to convert Xvid to Mpeg?

    Thanks
    Tom

    This kind of problem seems to be reported alot. Is this because the
    sampling rates in the audio files gets changed during the transcoding
    process and then you end up with a file of a different length?

    Virtual dub would allow you to extract just the audio file out of your
    video file. Virtual dub should pull out a PCM file, whereas you probably
    have MP3 audio in those Xvids.

    Often there are problems with trying to work with combined audio/video
    files, which is why lots of video editors prefer to work with what are
    called 'Elementary Streams', where they render out the audio and video
    files as separate streams and use those in their authoring program.

    You might try an MPEG Encoder.

    The newer ones like TMPGEnc 4.0 XPress will accept XviD
    as a source file. They have filters and provide a means of
    adjusting the sync, as well.

    Luck;
