Do you show 70% on both cpus if you use a load tool, like top?

As Hannes explained to me recently, the "Use only one CPU" option means
really to use a single worker thread to dispatch frame rendering jobs.  
They still get shared on multiple cpus.

What do you mean by 'use one or two cpus'?  I can disable a core in the
bios on an AMD X2 and have rendering take about twice as long.

If cinelerra is really only using one of your CPUs, you can run a
renderfarm node on the same machine.  But that should not be necessary.
