Create a video using PowerPoint?
 

I'm helping my mom make a DVD to play on a TV at her work advertising some of their products, the best way I know to make it look nice is using PP however I don't know how to turn that into a recorded video file without simply screen capping it as it plays.

Also what program can I use to make a DVD from a video file that will loop continuously so they don't have to hit play every 20 mins?

TIA
