Ultra YouTube Downloader Free is a free YouTube downloader. The app was designed to download videos from YouTube.com into your computer so that you can play those videos on any media player. To download a video, you simply have to paste its YouTube URL. There aren't really any options that you can change. All you can do is click on the "Paste URL" button and then on the "Download" button. Once you've clicked on "Download", the process should start, but, in my testing of this app, I got an error window every time I tried to download a video. I even tried pasting different video URLs, but with no success. I had had apps like this that did not work, but they rarely crashed when I had tried downloading a video.
When you are installing the application, you will be given the choice to carry out a quick installation or a custom installation. If you choose "Quick", the installation wizard will install a few toolbars and change your web browser's search engine.
So, basically, I like this application's design. I like how simple it is. I wish it worked, but sadly, it doesn't. Maybe, a future update will fix the issue. I use Windows 7. Maybe, other users will see better luck with XP.
