youtube-dl

Something I bet Mr. Chick-black-hole can't do (see below) is tell you how to get youtube videos on your hard drive. A python script called youtube-dl is all that's required. Check out http://www.arrakis.es/~rggi3/youtube-dl/ for more info but, basically, once it's installed, you type something like:

youtube-dl -l -a "http://youtubevideoyouwant.com"

into a command prompt and away it goes. The -l and -a flags mean "literal title" and "avi format," respectively. There are other options too, of course. Fricking rocks. They say there is a Windows port for it, but I wouldn't touch that with a dirty shwantzstucker. Works very nicely on my FreeBSD system. Anything with a python interpreter should do just fine. (btw, might wanna stay away from the pornotube-dl script. Prolly works, but that site is filled with a plethora of sex you don't want to see. Trust me, I look at pr0n for a living--I'll explain later. If you want pr0n, there are plenty of other places to get it).
