Yeah, I tried that, but I hadn't yet put in SR1 when I did these, and that part was broke. After SR1 it works, though, and good thinking. I used to teach computer animation, I was always seeing my students sitting in front of the Macs, watching it render, frame by frame. I used to tell 'em don't waste your time, if one is available even move to another computer and do something else. life is too short!
