I agree, but the first question that comes to my mind is wether or not 
the compression process can be broken into parallel operations. I don't 
know any of the particulars for the compression schemes in question, 
but for some schemes it can be a linear process, you can't fork it into 
two parallel processes.

The other question is how much of an advantage do you gain by breaking 
it into parallel processes? Again, without knowing the particulars of 
the compression scheme, its impossible for me to say (maybe someone 
else knows).

Before I start sounding too much like an Apple apologist, I'd have to 
say I would be as happy as anyone if I could be utilizing both 
processors in my Mac to their fullest potential when exporting to 
various QuickTime formats.
