Converting a PDF for use with DVD Studio Pro I have a client who want me to add PDF's to a DVD, so that people can view them through their televisions

Can it be done?
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.
