RCN YouTube Downloader is a free tool that downloads videos from youtube. It also allows you to convert downloaded videos into AVI DivX, Ipod, Iphone, PSP, Cell Phone and MP3. Unlike other similar services, YouTube Video allows only viewing video inside client's browser (YouTube's video player is designed to be used within your browser as an Internet experience), and currently you can't download videos to your computer. But it can be easily downloaded and converted to the common "avi" format with RCN YouTube Downloader.
