Sorry to bump this thread, but I'm not un-ignoring Ghostie-boy, so I may as well respond here:
It's called Google, dude. And Wikipedia. I know some here seem to think I know a lot about film/video because I go to school for it, and while that's partly true, the vast majority of this stuff I taught myself using the Internet even before I started going to film school. It's not that hard to find answers to the questions you've asked in the past.
Oh, and if you are Janskeet - you should know that I no longer live at the address you probably still have (indeed, I don't even live in the same state anymore). And no, I will not be giving you my current address.
Aaand now back to ignoring you.
