    Just got an IXUS 960IS and I am not sure if the following is normal when
    taking movies.

    Any movie that has a slightly brighter area than the rest of the scene,
    i.e. a window/part of a window has lots and lots of purple/blue vertical
    lines running right through the frame from top to bottom, in some cases
    it's a purple bar the width of the window or brighter area. Is it normal
    for one of these compacts too suffer so badly from what I think is termed
    vertical smear? This make the camera almost useless for taking movies
    indoors with windows present and captured in the frame. (The same scene on
    an S2 show no (or extremely little) vertical smear.)

    I think it's the same thing. If you point the camera at a light source such
    as a light globe you get a single vertical line. Now imagine a bright
    window and I get a vertical band the width of the window. The single
    vertical line I think is due to the way CCDs work.

    Sounds to me like it is, and was (is?) a common problem in
    astro-photography where a very bright star is included in a field where
    a long exposure is trying to capture faint objects. The suggestion then
    (I am out of date on this subject!) was "put the bright star out of the
    field of view" - not always a helpful suggestion!
