It would be very useful to be able to embed the html to include YouTube videos or, alternatively, embed video right in the pages. Have you considered adding this feature?
Such feature request already exists. As for now, you can put your Youtube video using Script module. Just add Script module into Sitebuilder and add youtube link into it. For more information about how to work with Script module you better refer to Sitebuilder manuals: http://www.parallels.com/en/sitebuilder/docs
You can also check some example provided by one of the forum users: http://forum.parallels.com/showthread.php?t=61392&highlight=YouTube
Hope it helps.
