You would have been using video capturing websites like KeepVid to download videos from video hosting websites like YouTube and Google Videos. But they are downloaded only in FLV format. And then you have to get another tool to convert those FLV files to playable media format inside popular video players like Windows Media Player or Winamp for which you may have to pay.
Now you can directly convert and download those YouTube videos online. Vidconverter.com lets you provide the URL of video and it automatically converts video into downloadable MPG format. The quality of videos converted is quite good and it doesn’t take much time to convert videos.
