Shift audio track vs video track using Windows Movie Maker - possible?

    I'm using Windows Movie Maker version 5.1 on a new Dell WinXP Media
    Center, 3.4 GHz, 2 GB RAM system.

    I've successfully recorded video/audio from my analog VCR into my
    computer. The audio outputs of my VCR were Y-cabled not into the TV
    tuner card with the video cable, but into the computer's sound card,
    an SB Audigy 2ZS Audio (D8CO). The audio track appears in the "Audio"
    track when viewing the Timeline, not the Audio/Music track - I believe
    that's normal.

    However, the audio track is a split-second before the corresponding
    video.

    Question #1: how to shift that audio track very slightly and synch it
    up perfectly to the video? My guess is that WMM can't do it, so if
    that's the case, what is the best software to get that will do the
    job?

    Am not sure whether the video itself has an audio-shift problem. Am
    about to do more homework and find out whether it was the source,
    whether not going into the TV tuner card's audio IN made a difference,
    etc., but wanted to find out about WMM's audio-track-shifting feature
    regardless of this current problem.

    Question #2: How, using WMM, can audio be cleaned up using a different
    program (such as Cool Edit Pro) and then precisely pasted back onto
    the video track?

    It seems to me that WMM can't separate the audio track from the video
    track. Thus the audio track should be recording into a different input
    (mic?) so that it appears in the Audio/Music track, not the Audio
    track. Is that the best solution?

    If there's a better program, will it be able to read the .MSWMM files
    created by WMM or will the video have to be recaptured?

    Thanks for all suggestions...

    If you want to split the audio and video tracks within MM,
    simply drop a copy of your movie on both the video and
    the audio/music tracks. Then mute the sound in the video
    track. You can then shift audio/music track to try to
    sync it up with the video.

    If you want to try to extract the audio, just drop the
    movie on the audio/music track only. Then when you save
    your movie, it will create an audio-only WMA file. You
    could then import that into some other program to clean
    it up.

    NOTE: I've trimmed your crossposting distribution to include
    only the microsoft newsgroups.

  3. When you capture analogue via sound card and graphics/video card the
    different items are processed differently, which nearly always ends up with
    sync problems. The only way to get rid of this in capture is to invest in a
    quality analogue to digital conversion device such as canopus or miglia.
    As Bob has said you can export audio only from MM which can be taken into
    cool edit pro for editing and then placed back in the timeline.
    Only MM can read the MSWMM file as this is the movie maker project file, not
    the movie. If you export the movie as an avi then all other editing apps
    will be able to work with it, but the sync problem will still be there, as
    this was done at the capture stage.
