With regard to the "line" that you're seeing, do you have all your
power cords plugged into the  same AC electrical phase? Cameras use
the 50/60 cycle AC to sync there signals on. If the cameras are
plugged into a different phase than the computer or from each of the
cameras, you might wind up with a line across they screen. Also, if I
remember right, you run on 50 cycles there. The board my be a 60 cycle
board. I don't know if you have polarized AC plugs on your camera
power supplies or computer or not, but sometimes reversing them can
help. Other than that, I can't think of anything else.
