There are too many ways to do this but beware those that spam the forums with their payware.
Simplest method? Use a screen recorder, play that powerpoint then edit the capture then make your DVD. You didn't tell what DVD software you had so I'll note DVD FLICK.
Is there a way to convert a powerpoint slideshow with music to DVD for television viewing? I believe I can do it so it is viewable on PC but not TV. I used powerpoint 98 but have since upgraded to 2007 on windows xp. Any help would be appreciated. Thanks!
