I want to add videos to my blog...having trouble though.

  In my Enthusiast Blog, I want to be able to show my readers videos without having to make them leave the blog.  Does anyone out there know how to get a video in the blog?  Is it anything similar to adding an image?  I can always just add a link, but I think aesthetically it will make the blog look much better...don't you?  If anyone knows, let me know!  If not....I guess I can just work with the old fashioned way and use a link to youtube.
