This is a Free and Fast way to grab just about any video from the Web. YouTube, DailyMotion, Megavideo, Metacafe, and Vimeo are just a few of the sites compatible with KeepVid.
Copy the URL of the video you want to download, head to KeepVid.com, and paste it in the bar at the top. Then click "Download" to the right of that bar. Do not click the large green "Download" button.
It will load for a few seconds, then you'll have the option to download the video in FLV (Flash), MP4, or WebM format. If you don't know which one to pick, go with MP4, as it has the greatest compatibility.
