Embed Web Videos (Vimeo, Dailymotion, etc)
Directly insert Web Videos into your PowerPoint presentations just the way you embed videos in web pages.
Copy/paste the Embed Code provided by the video sharing site into the 'Insert Web Video' dialog box and playback
the video during the slide show.
Web Videos have successfully been tested with YouTube, Dailymotion, Vimeo, Metacafe, veoh, viddler, blip.tv, Myspace, break.com, archive.org.
Many other online video sites that support the embed code will also work.
