YouTube Downloader is a program that lets you download FLV source videos for any of the movies you see on the YouTube site. It is a free program that you can download from here...
Once you install the program, follow these steps to download YouTube videos with YouTube Downloader:
Launch YouTube Downloader, and enter the URL of the YouTube page that contains the video you want to download (see Figure 1).
Figure 1: Add the URL of the YouTube page that contains the video
Make sure that the Download video from YouTube radio button is selected, and then click OK.
YouTube Downloader will show you a File Download dialog box (see Figure 2), and ask you to choose a name and location for the downloaded FLV movie.

Once the download is done, you'll find a FLV file in the location you saved it to. If you find that the downloaded movie has no file extension, rename it to add a dot and the extension "flv" -- so that get_movie reads as get_movie.flv
Remember: YouTube Downloader is a constantly updated product -- sometimes YouTube might change a few things on their site, and YouTube Downloader may no longer work. If that happens, check the YouTube Downloader site for a newer version.
