It's software that allows you to download videos from YouTube, including HD and HQ videos, Facebook, Vevo, and many other sites and convert them to other video formats. The program is easy to use, just specify the URL for the video you want to download and click the Ok. It also allows you to convert downloaded videos for iPod, iPhone, PSP, Cell Phone, Windows Media, XVid and MP3. Allows you to access YouTube videos for which you need to be 18+ years of age. Now, plays videos downloaded.

It is really cool. It's nice to have a software that can download videos from YouTube, but especially other web sites that have videos you can watch as well.
