aTube Catcher, which is the name of this new version, can be used not only to download videos from YouTube, although we have to admit that it's the first site we go to watch all kinds of videos: music, movie trailers, video tutorials, walkthroughs, and youtuber reviews. It can also be used to download contents from video sites like Vimeo, Facebook, Dailymotion, Metacafe, Spike, Yahoo!, Globo or RTVE. And, of course, webs that host porn videos.
