I have ppt with Office98 and you can import Quicktime movies into your presentations and also use image files for slide show presentations and backgrounds. The Powerpoint file can also be exported as HTML for use in web-browsers. You can create slide shows for the HTML version but I'm not sure if you can imbed the movie files within them. Apple has a PowerPoint-like program that can work with existing ppt files. I don't know if you can export as ppt though. I use MacOSX/9 but don't really use powerpoint except to see what it looks like. It's one of those boiler-plate programs that creates content that all look the same. I guess that conformity is its appeal.
