Converting a PDF for use with DVD Studio Pro
Sure. You need to convert the pages of the PDF into images and handle accordingly from there, much like a photo slide show. The primary concern I would have is whether the PDF is laid out so that it looks good on screen.

Acrobat (the full version, not Reader) can export all pages to a variety of formats. Acrobat costs good money, but Preview only exports the first page. Ghostscript via Terminal might have a free alternative, but the interface is the command line.
