I've posted about Rouxbe last year, but have just received an email saying they have just turned one this month and are now in 180 countries.
Rouxbe is the web's first-ever online video cooking school complete with practice video recipes, cooking exercises, culinary quizzes, progress reporting and personal chef support.
For me, Rouxbe, is one of the best, if not the best example of the use of video in learning, so even if you don't like cooking, you should take a look at this site. Even better, is the fact that you can now set up a free account.
Here's just a taster of the quality of the video, although you need to access the site to see the exercises, quizzes, discussions etc.
