What version of iMovie are you using? What version of iLife do you have installed?

You cannot run the iOS versions (for iPhone, iPad and iPod) on any computer - they simply are not compatible with any computer operating system.
You need the OS X versions for your powerbook - you should have gotten an iLife disc with your powerbook, which you can use to re-install the original versions if you have deleted them.
