Powerpoint Addict!

Yesterday in school I started to make a powerpoint for the child that I support.  I was able to insert pictures from the internet and hyperlink buttons to turn the pages.  I also used hyperlink on the contents page so that when you click on a topic, it takes you straight to that page.  I inserted a home button so that you can go straight back to the contents page when required.  I couldnt remember how to insert a video from the internet so if anyone can help it would be appreciated.
