    my problem is that setings on projector.
    it has 5 setings theater presentation ect.
    but when i connect the Scancom XGA Theatre
    with the suplied lead vga cable.
    i then switch projector to pc mode and great picture from
    cablebox is great bright and clear.
    but i canot get it to go 16.9,
    there are 2 other setings on projector menu for pc mode.
    these include component video (ycbcr) and (ypbpr).
    switching to any of these modes gives me 16:9.
    problem ? all white content of picture turns redish purple color.
    i am prety new to this and would realy be greatfull for help.

    ps i tried switching modes on cable box composite and rgb.
    16:9 and 4:3.

    Sorry, I'm a bit sleepy and maybe not picking you up right.....

    The cable box is connected by scart to composite?

    What are you connecting with the supplied vga cable?

    What is it that you wish the 16:9 mode to do? Surely with a 4:3 projector, the 16:9 mode is really only used with anamorphic material so would do noting for cable material? Forgive me if I am wrong, I am obviously referring only to what my projector was like.

    All the best

    ok scart from cable box to 3 phono yelow to Scancom XGA Theatre
    vga cable goes from Scancom XGA Theatre to projector,
    looks like ile have to get another screen for sky viewing.
    the screen i have is 7ft widescreen.
    could you explain what these modes do on projector.
    component video (ycbcr) and (ypbpr).
    both these setings bring down picture size to fit screen.
    but picture goes red and purple color.
    is there a way of using these setings before i get another screen.
    converter ect.
