While I have not used Handbrake, my wild guess from your description is that it does not share processor cycles nicely. It is using all the cycles it can on one processor. Say it is chewing up 90% of the 1.67 and 500 processors. That only leaves 10% to play, which is pretty pitiful to play a video. On the dual 533, OS X forces it to play nicer between the processors. So that it may use 90% of one, it still leave the other processor free to play the video.
