Hi, Gary. Apple announced a number of years ago that it would no longer support OS 9 or its old OS 9-based software applications. At that time it had already supported them for several years after introducing OS X, and there comes an end to everything. So not only is your obsolete version of DVD Studio Pro unsupported now, but so is the Bias Peak 3.0 bonus package that was bundled with it. There is no one at Apple any more whose job description includes supporting those antiquated products, and it's even possible that there is no one at Apple now who ever was involved in supporting those products. Consequently, I'm afraid you're going to have to get along without using Peak, which you weren't expecting to receive with your purchase anyway.
