  1. Hi!

    I'm trying to extract the audio of the above-mentioned film,but when i press "save Wav as" I get a message that says : the requested audio compression is not compatible with the input informat. Check that the sampling rate and the channel count of the input match those of the trequested format.

    What changes do I have to make?
    I'd be gratefyul for some help.

  3. I have same problem with Windtalkers and Minority Report. The file info in both cases says:

    Compression: Unknown (Tag 2000)

    It's allways with new movies. Someone knows if there is a new plugin arround?

    Both of your problems are because the audio file in the film that you are trying to extract IS AC3 ( dolby digital )

    You CANNOT extract ac3 with virtual dub as far as i know even if u have the ac3 codec installed

    You do not need a plugin you need a program called GRAPHEDIT to extract the audio

    Do a site search for "GRAPHEDIT"

  5. Well, I got GraphEdit. But I'm to stupid to use. I can't find a working praph to convert avi with ac3 to avi with regular stereo sound. Can you tell me which filters to use?

    u need to delete all the filters after the morgan stream switcher on the audio side

    Add 1 file writer and save it to anywhere you like when it asks

    Then add 1 wave destination


    Morgan stream switcher------------->Wave destination---------->File writer

    Then press play in the menu at the top and away you go

  7. Thanks. This seems to work (LoL. My system is blocked for hours now). One more question. Can I delete the video side after the splitter? I'm not really interested in watching a movie without sound and it may increase speed.
