The champion of video downloaders Puntuado con 5 de 5 estrellas
I tried the others (Keepvid,Download Embedded,UnPlug,OrbThis,Google Video Downloader,VideoDownloader,Video Download,Ook? Video Ook!,Media Pirate,Fast Video Download,GetVideo).
Yes I have tried all of them. Although I didnt do extensive evaluations of every single one of them, and some of them have features I didnt try, I did download a video from all of them and this one seemed the most natural and easy to use.
