MacOS – What software for video editing should a G5 Tower Use

I use Adobe InDesign for this kind of thing... more flexible than AcrobatPro. Allows total control over what you import into the pdf (text,images, other pdfs, etc.) and the ability to create clickable TOCs. If you are going to do a lot of this, or a lot of print, it is worth the investment.

I can recommend Final Cut Express and if you want it real pro - Final Cut Pro. Note that a major new Final Cut version is nearly out - probably with the MacOS X Lion. Also note that some price drop is expected for both products, probably you should wait a month.
