Jeff Thomas raises a good point - there is so much video online, but it's not always easy to find the video you want. Just searching on YouTube or Vimeo might not be the most effective strategy. He recommends 10 video search engines, and an iPad app for watching video on the iPad. Video search engines include the usual suspects - Google Video, Yahoo Video, Bing Video, but also some I haven't heard of, like Fooooo, Blinkx, and VideoSurf.
Oh, and if you're looking for those specialized videos about technology in adult education, try OTAN's Video Gallery, which now includes the Captured Wisdom videos about adult education technology-based projects, or the Media Library of Teaching Skills (MLoTS).
