Multiple processors

I have a screaming Quad Opteron system with 4 GB of memory. Unfortunately, it seems that CloneDVD only knows how to use one CPU. IS there any way to configure it to use more of my systems resources? Is three any DVD ripper out there that is multiple CPU aware?

I would like this added as well, and also the option to crop. Most times its the codec that sets if you can use more then 1 cpu core. Not the GUI of the front end app.
