Adding YouTube videos to your iWeb site: "Including YouTube videos on your iWeb ’08 site is easy.
In iWeb, choose the page where you want the video to appear, click the Web Widgets toolbar icon, and select HTML Snippet.
Next, go to www.youtube.com on your browser and choose a video. In the box to the right of the video, you’ll see a field labeled Embed. Select the contents of the Embed field by clicking inside it, then select Edit > Copy from the menu bar.
Back in iWeb, click anywhere inside the large gray HTML Snippet box, select Edit"
