Lessening processor usage

[Karl Becker]

I've brought up this topic earlier and didn't get any responses, let 
alone a satisfactory answer.

Why does MetaCard's processor usage spike horribly after playing a 
QuickTime object?  Even if the player is stopped, or hidden and 
stopped, the processor usage still is quite inordinate.  Is this a 
"feature" with MetaCard, or am I doing something wrong with player 
objects?

I notice the processor is used a lot even when I use the "play 
videoClip blah.mov" to do a one-time sound where no player object is 
necessary, though processor usage doesn't seem to be eaten up by it as 
much.  However, as the program is kept running for hours, its processor 
usage does go up.

Ideas?  Thoughts?

Thanks,
Karl
