In order to change the jpg settings in the library, you need to uncheck the "use imported .jpg data" box. Then you can change the percentage, veiwing the changes in the upper left as you make them.

But I suspect the real problem is the PII system you are trying to run on. It's likely an issue of the PII not having enough memory on it's sound or video card to handle all this action. I've run into the same issue, there's not much you can do when it's a hardware issue.
