You'd think Apple would multithread... right?

My kid sis just had her birthday party, and we hung out (as bro's and sis's do :-) and made a DVD together. It's the first time I've really spent a lot of time working with iDVD (I've used it once or twice before, but nothing fancy).

So as I write this iDVD is crunching away and rendering menus, slideshows and movies... and it's only using ONE of the cores in my laptop... Which doesn't make a lot of sense, given that this whole video rendering process is about as heavy a task as most computer encounter.
