Whether you know the tool Video Downloader Converter(http://www.downloadallvideo.com/video-download-suite), which turns up in the articles of a video download site frequently. I just know it from this place, this tool has two different ways to save online videos, when I want to record streaming video, I straight run the built-in recorder when I watch the video online, it will automaticlly detect the video, after popuping a window, change the title of video and hit "Add to download list" is ok.
