I think screencasts are as good as the presenter. The best screencasts are much like a good 10 min pitch. They should tell me the problem, show me the solution and leave me excited and wanting to find out more!

One of my favorite ever screencasts was Rob Conery's on BDD with C# with the MSpec framework[http://blog.wekeroad.com/mvc-storefront/kona-3/] It was put together so succinctly that it really clicked with me what BDD was all about and I came away wanting to download the tools and learn more!

If your screen cast is on Vimeo you could add the little bookmarks on the video time line. This could help users skips to sections appropriate to them.
