Distributed DVD Back-up Solution?

SoBeIcedT asks: "I just bought the third season of 24 [fox.com] on DVD and have begun to back it up to DVD+R using DVD-Shrink on Windows XP. Being the gadget loving guy I am, it makes sense that I would have multiple computers. The trouble is I can't make use of all of those CPU cycles and they go to waste. Is there a way (perhaps using clusterKnoppix or something of the sort) that I can easily use all of the processor power in my home to transcode the DVDs?" dvd::rip is one option that has clustering support. Are there any others?
