I have the exact same question. I've done web searches on how to do this, but a lot of the information I find is several years old, and some of the programs and suggestions are completely out-dated. If anyone has a current way to do this, I'd really appreciate hearing from them! Thanks.

I've had 'some' success with a program called PPTonTV and even tried using Windows Movie Maker but with both, the screen aesthetic value of the final product was disappointing. My monitor version of PPT was far superior to the final product on a conventional television.
