GotCLIP is a good application for downloading videos from websites like Youtube, Vimeo, DailyMotion, etc. in a very easy way. You'll only have to copy the URL of the video you want to download, paste it in the text box, and click 'start' button. The only noticeable issue in this app is that the downloaded file will be formatted as it is in the website, usually, FLV, so you'll need a media player that supports that format. GotCLIP is one of those applications that offer you that missing download button in Youtube.
