How you can download videos from YouTube?

Yes, absolutely. I don't know why the previous answer was simply "no" when that's as far from the truth as can be.

I use a program called freecorder, and much to the tune of it's own name - it truly is free. it will download video, record audio, and convert to all the popular formats, including MP3, iphone/iPod/ipad, MPEG-4, Windows Media and more
