To save PowerPoint on DVD and play on TV or autorun, you may need a
PowerPoint to DVD tool such as
Wondershare PPT2DVD from http://www.ppt-to-dvd.com
It can create DVD from your PowerPoint presentations
DVD players need video formats, they can't play PowerPoint. I like to use
Camtasia Studio, www.techsmith.com, to turn my presentations into videos. It
has a PowerPoint-Add-In that makes it easy and it gives the best results.
