How do you put videos from Youtube onto Microsoft PowerPoint 2003?

Natively, you could provide a link in the PP presentation to the site video <A Href> but other than that you could:

Download the actual video using a downloading tool made specifically for you tube or video site.

Convert the video file to a usable form IE Mpeg 4, WMA, or AVI.

Then place the file into the PP and use as needed.

Hope this helps - If you need more drop me a email or hit me here.
