Converting Videos on Mac

I recently stumbled across ffmepgX. (http://homepage.mac.com/major4/) It's pretty sweet. Forget Podner or whatever you've been using illegally, this is open-source and therefore totally free. The nice part is that it queues compressions/conversions. If you have more than one core, you can have simultaneous operations in progress. I suppose you could do the same with one core, but why? That'd be really odd.
