Hi Graham,
Even though buffering eliminates flicker, it takes up
cpu-time and memory, so that may actually be slowing
the display down, especially in low-memory situations
where the OS has to swap memory to hard disk.
As for overlapping: what I mean is if one of the
rectangles goes straight 'through' a player object ?
Because then RunRev has to do extra work: it has to
get the frame from QuickTime, and then draw the piece
of rectangle over it, and it has to do it every frame
it shows.
