Dcmoser,
By rights, being a professional photographer and designer, used to using Photoshop and Illustrator and InDesign, designing a web site using a program such as Dreamweaver should be dead easy. But it's not! I could never get to grips with almost all the web design programs on the market. They were either too simple and the results reflected that, or too complicated and I just gave up in frustration.
Then along came iWeb and I was hooked. Like most Apple programs it did almost everything I wanted - easily. Sure, there are always little niggles and extra goodies that one would, in an ideal world, love to have, but by and large it does just what its says on the box. I have had all the various updates and produce two sites with the program. Perhaps an "iWeb Pro" would be the ultimate goal, but I'll live without it.
Beginner friendly it certainly is, although it won't be long before beginners wish to ditch some of the Apple templates and ways of doing things and add their own versions. There are so many great links through this Discussions site that you'll never be short of ideas and solutions. I must admit that I do not have much to do with embedding video, but I'm confident that there will be someone reading this who will know the answer.

Both done using iWeb '09 by someone who finds Dreamweaver as complicated as a Tax Return!
Good luck!
