I recently converted a powerpoint to DVD, but did it all manually in DVD studio Pro. It turned out very cool, and I think I will just start there from now on. I used menus instead of slides which allows you to use animated video backgrounds, and DVD transitions between menus. I also have lots of video in the presentation, so going from menu to a video was a snap. At the end of the video, it simply advances to the next menu. The menu then plays until you advance to the next menu which is your next slide. You need a working knowledge of DVD studio Pro, and it takes a bit longer to set up, but it makes for a very dynamic presentation that can be played on any DVD player. I am guessing that if you export quicktime out of powerpoint and burn it to a DVD you lose the ability to advance slides back and forth, and instead have to pause the DVD during playback? With DVDSP you can build a controller to advance back or forward or take you to a menu with the outline of your presentation.
