I believe you would want to check out "TVCD" at waw.tvcd.biz .This program costs US$25, but does have a FREE feature-limited DEMO, which allows pictures to be imported from Powerpoint automatically.
Or you can if you have Nero-5, save, using save as, the slides you made with PP in JPG-format. nero will accept the jpg-files
Good luck
