In PowerPoint, save as JPEG files or as PNG (portable network graphics) will create an image of each slide. You can then place the images on the timeline and manipulate them anyway you like. You may need to reconstruct embeded sound and video files. I don't know how this technique will handle builds where you add information to a slide in steps.

I have used this with a simple presentation very sucessfully.

EDIT: I have also used a scan converter. I record presentations live with a small video mixer and feed the scan converter into one input, so I can switch between the presenter(s) and the PowerPoint images.

I belive there is a product called camtasia that is worth checking out.

Camtasia does a great job of this. I used it on a presentation last year and was the easiest method to almost duplicate the original presentation.

This comes up often. Do a search in the subject heading for "Powerpoint."

Here are two past threads:

ATI 8500DV ( or similar card) to miniDV tape. Tape to Vegas. We do several of these a month this way and, if the PP presentation has been saved to CD using the "Pack and Go" feature, transitions, music and video clips will transfer across from the computer to tape.
