Go directly to the point, for example you want to dowload Kaley Christine Hot Video from youtube, the video url is: http://www.youtube.com/watch?v=z7omc76GFV4
then, replace the "Y" letter of youtube with the "3" number,
Must be like this: http://www.3outube.com/watch?v=z7omc76GFV4 - Enter
3outube.com site will provide download links of the video in MP4 or FLV format.
Or you can also go directly to 3outube.com site , and enter the video link that will be downloaded, and press download button
Very easy way to download youtube files
