If you incorporate video in any of your online work, you might want to take a look at Embedr. It's "a free service that lets anyone create a custom playlist of videos from the top video sites on the web." That is, you can take up to 100 videos from all over the web and make them into a single standard playlist.
Here is the list of video services compatible with Embedr. And did I mention it's a free service? You'll be asked to set up an account, but it is free. And BTW, you can embed your Embedr playlist on your Facebook and MySpace pages, too.
At your service,
