Microsoft Expression Web For Dummies
For your visitors' viewing pleasure, YouTube makes it easy to upload short videos and either link to them from your site or embed the video right in your page. (See http://www.youtube.com/sharing.) You can even include a scrollable list of videos and let your visitors pick which ones they want to watch.
Google Video also provides a great method for making your video content available to visitors. (See https://www.upload.video.google.com).
For other options, check out David Crowder's Building a Web Site For Dummies, 2nd Edition (Wiley), for complete information about including video on your site.
Linking to videos that someone else has uploaded to YouTube or Google Video gets a little more complicated due to copyright issues. Know your rights in case the person who uploaded the content stepped on someone's copyright toes. If you're located in the U.S., bone up on the laws of fair use at the U.S. Copyright Office (http://www.copyright.gov).
