How to make system use 100% CPU resources?

[PeterCH]

OK I often render stuff or convert MOV SD DV to .M2V/MPEG2 files
for burning to DVD using Compressor, DVD Studio Pro or even iDVD.
When I check on how much of the system resources are used,
the system always has 33% free CPU resources even when
the render takes long. I use a dual processor, dual core Intel Xeon.
I'm sure that people with C2D processors also have this problem.
So does anyone know how to tell Mac OSX to use 99% of the CPUs
and render stuff a bit faster?

I notice that some apps utilise the available cpu resources better than others. Doubt there is much that can be done until the software and os better supports multiple processors - here's hoping Leopard isnt too far away. :0
