jit.matrixset question - loading from a single frame movie?

    Hi All,
    I'm trying to understand how to load two single frame movies into a jit.matrixset which has matrix count set to 2.
    The idea is, I load movie 1 into matrix 1, movie 2 into matrix 2, then later, load a different movie into matrix 1 without affecting matrix 2 etc. I then display one of the 2 at any time.
    I'm not sure what messages to matrixset might do this. (At any given time I load other single frame movies into either "slot" and display the still image)
    Also since they are single frames - essentially stills, is it better to use QT .mov's for this, or actual still image (.jpg or .png) files?
