"KeepVid" to easily download from Google Video and YouTube

Sites that can download from Google Video or YouTube just paste the target address


Google Video
http://video.google.com/

YouTube
https://www.youtube.com/

For example, suppose you have such a movie.
https://www.youtube.com/watch?v=gY1JRPFK9-E&search=Hanuman

Open this page, select "YouTube", and paste it on the form.
http://keepvid.com/

And then click on the "DOWNLOAD", because out is that "Download Link" saved by right-clicking on it, the extension from in the ".flv", not being able to play throw some players that can play.

Playback player seems to be able to use FLV Player or VLC media player.

FLV Player

Personally, FLV Player may be easier to use.
