    I have avi files of an 80's TV show that I am attempting to burn onto DVD's.

    I tested the avi's for bad frames and none were found.

    I have extracted the audio with GoldWave, cleaned it up, and saved it as a 48,000hz 1536kbps wav file. The video was resized to 352*240 mpeg2.

    After burning onto DVD, the audio is out of sync. Most of the references to this that I have been able to find have to do with bad frames. Is there anyway this can be corrected?

  2. Check the actual video length in gspot.
    Extract the audio in virtualdub or goldwave.
    Check the actual audio length.
    Open audio in Goldwave/SoundForge/Audacity, and expand/contract audio to match video length exactly.
    Remux/author/burn.
    If the audio is still out of sync, then there is either a portion of audio missing, or a portion of video missing, or a section of "dead air" in the audio (usually right at the beginning).
    Remove one or two seconds (however much you think it's out), then expand the remainder to macth the video, or add some dead air at the beginning, then contract to match video.
    It's not an exact science, and there's probably 200 guides telling you how to sync video to audio, but every single file is different, so what works on one, may never work on any other.

    I forgot...I've already check that also. It appears to be OK, although GSpot will show the time as like 46:07, and GoldWave will show the length 46:065. GSpot doesn't seem to be as exact as GoldWave, but if you round it off, it would be the same.

  4. OK, the extracted audio is the same length as video, BUT, it's still out of sync. (been there done that).
    If audio is BEHIND the video, then you need to cut a bit of audio and stretch it to fit video.
    If audio is AHEAD the video, you need to add some dead air, then shrink it to fit video.
