Just for you all to know:

I hope you don't download rubbish scu, program which make you download their viruses for sake of downloading after a while youtube vids. so if you ever wonder how to download YouTube legally without any hursh, 
so just foloow that little advice. 
if for example you had that video on YouTube: http://www.youtube.com/watch?v=7QgaFtxlLMM
so all you have to do to download it easily, it's just to add ''ss'' before the word 'youtube'.
so here we go: http://www.ssyoutube.com/watch?v=7QgaFtxlLMM as you see i added 'ss' with the same URL, 
and now i can insert it in my browser and that will get me into dowloading the specific YouTube video without hassle.
