    I've bought an rf modulator box to get the scart output from my digibox into
    a television that only has an rf-in, all seems to work fine except when the
    picture brightness is very light (when the screen goes white with just black
    text for instance). The picture seems to have a kind of effect I can only
    compare to poor tracking on a vcr in that the picture is offset to half way
    down the screen and this flickers intermittently between that position and
    where it should be. Could someone suggest why this is and what I can do to
    remedy it?

    Some modulators have a termination switch for the video on the back of the
    unit....... usually it should be in the 75 ohm position, not the 1K
    ...... Or you could try a different modulator..... or a different brand.
