I've been hunting for days now in order to find a simple trick so I can easily download videos from youtube .
There are a lot of them including software tools , firefox plugins , many scripts etc.. Well most of them are good at doing their work .

But I will mention a way that it's the easiest that I've found. This way includes using http://www.tubeleecher.com.

Ok here are the steps involved

1) visit http://www.tubeleecher.com
2) get the youtube link you want to downlod
3) paste it in the textbox on tubeleecher web page
4) press "Download" and save it

You can watch the video you just downloaded with a flash player.
