    I am a composer and i'd like try composing for picture. As an
    exercise, i'd like to create video from commercial DVDs but without
    the music : just having the video and the dialogs and snatural sounds
    like the cars in the street, for exemple.

    What method, software would you suggest to use ? (I don't know much
    about video editing, so please ... something straightforward if

    Many thanks

    It's very common for multichannel DVDs to contain only dialog in the
    center channel, so just deactivating everything but the center channel
    during playback would get you dialog only on many movies.

    But most movies don't separate the music from ambient sounds and sound
    effects, and there won't be a good way to do so after the fact. Sound
    effects and ambient sounds occupy the same audio spectrum as music.

    If the disc is Dolby 5.1 or better you may be able to extract a clean
    dialogue track as this is normally but not always assigned to the centre
    track. The music and effects are spread between the front left and right
    channels with special fx to the surround channels. In the case of the music
    and fx mix you can't really 'unscramble' the egg to give an analogy.

    If the disc happens to be only stereo then there is no way to extract centre
    assigned information, you can get a Left minus Right that by definition does
    not contain any common material ie centre assigned sounds.

    If it's mono then in the words of the famous line from "Planes Trains and
    Automobiles" "yer f***ed!"

    Sometimes as a special feature in the Extras you will get a clean music
    track etc - so it varies from disc to disc.

    Many thanks for your answers Rich and Stuart ...

    I forgot to precise, i want to create an avi file in order to import
    it in my music sequencer.

    Which straightforward software do you suggest to use in order to
    convert the DVD to an avi file with only the center track and the
    video ?

    Probably AutoGK to make a avi or xvid file. However you are going to have to
    do some sound editing to extract the centre track info from the Dolby 5.1
    sound track. This is not a simple process, because the 5.1 channels of audio
    are combined in one file so you will need a sound editor like WaveLab to
    extract the individual tracks. Then you will have to sync this track up with
    the video. I suggest you visit forum and ask there, you
    will also find some useful freeware software that might help. Another forum
    worth visiting is
