    Ok something is confusing me, I have this file here....

    .avi

    102,892 KB size
    640x480
    11m:36s

    Audio:
    Bit rate: 127kbps
    MPEG Layer-3

    Video:
    23 frames/econd
    147kbps
    24bit
    XVID Compression

    Now I'm kind of confused... I calculated the overall data rate to be 1200kbps or so... yet those only seem to add up to 300kbps... how are you suppose to calculate this stuff?

    Yah it doesn't add up dduardo :) The video should have been 1200kbps using the real size and time but the two bit rates dont add up to that.
