Here we go...
Open YouTube and select your video.
Now copy the URL of that video. For example if this is the URL of the video: http://www.youtube.com/watch?v=IbGXYn4SmwQ
Now paste it on a new tab and after "http://" add "ss"(without the quotes).
For example:http://ssyoutube.com/watch?v=IbGXYn4SmwQ
Note:- Remove 'www.' if it is there in the URL..and if you are downloading from a mobile, the link will be like this:http://www.m.youtube.com/watch?v=IbGXYn4SmwQ
Remove the "www.m." and add "ss"(without the quotes)
NOW hit enter and choose the format you want to download the video in,, like Flv,mp4,3gp etc. Select your desired format and download.
Alternatively.....You can use this other trick to download youtube videos or any other video.
Just add "sfrom.net/"(Without the quotes) before the URL of the video you want to download.
For example: sfrom.net/http://youtube.com/watch?v=IbGXYn4SmwQ
Enjoy.
