jit.dx.grab write to disk codecs

    Feb 27 2006 | 10:16 pm
    i'm trying to write on disk some video with audio
    in differents formats, with the jit.dx.grab object.
    I think that I use the correct synthax
    (like:"write c:testvideo 25. mpeg4 max") but the video layer
    is allays compressed with "no compression",
    or in "yuv" if I change the "format" of the grabber.
    (I'm using QT6.5 on win XP)
    how can I really compress movies in the correct codec?
    another question is:
    Howcan I've got the video signal out during the writing?
