Where can I download the video How It's Made ?

hell0! do you mean "How it's made" on discovery channel? if so, i think you can find it in the most big torrent reactors and also on youtube probably, because it is really cool and i am sure that there is at least one person who have ripped it from the TV and upload it in some of the torrent reactors. try rapidshare.com, it is one of the biggest and most famous ones!
