Jit.qt.grab to jit.rota resolution problem

Hi all, just wondered if anyone could give me some insight. I'm using the patch below with camtwist (you can try with built-in cam if you don't have it) to take an image of my desktop and then jit.rota to split that into 4 sections. My problem is that the resolution is predictably bad when sent out to the four different windows. Is there any way I can reduce the loss of resolution or think of another way around it. I realise I will lose some whatever I do but right now this just can't forward until I find a solution. p.s. I am not using jit.desktop as it's a cpu eater.
