There has been posts about converting PowerPoint to DVD- I use this software for many of my corporate clients and it works great- and under $50!!! http://www.dvdxcopy.com/point.asp
I always use a scan converter, that way it keeps the entire presentation intact with timing and transitions and audio. It's much less of a hassle than converting to stills and trying to rebuild everything.
Jsnkc... thanks for the feedback. As an FYI (without sounding like I work for them) This software does not do stills that you have to then re-build. It actually builds the entire presentation with transitions to a finished DVD that can be worked using the DVD remote. It is a very slick program.
Hmmm, maybe I'll have to check it out. The only think it seems laking in is the output, seems you're stuck with DVD. It would be nice if you could output it as a AVI file.
