The scooby thread is a comparison between 9006 and HIR bulbs showing the difference in brightness, as dazz32 was enquiring about it, nothing to do with HID there, sorry if there was some confusion.
Yes the video is old, when HID just started appearing on the market and prices were high. Prices have gone down significantly but the science behind HID retrofit kits haven't changed.
"From time to time, I am asked to comment on what are marketed as "new developments" in HID kits, and those asking sometimes point out to me that these "new developments" might render this article out-of-date, since the copyright date on the article is older than the date of these "new developments". Please understand, marketeers will always be coming up with dazzling new pseudoscience, tempting new hype and sneaky new ways of trying to convince you to buy their stuff. It's what they do. This article will never go out of date, because the problems with HID kits are conceptual problems, not problems of implementation. Therefore, they cannot be overcome by additional research and development, any more than someone could develop a way for you to put on somebody else's eyeglasses and see correctly."

Again I stress I'm not going to stop others from using HIDs, I'm just saying there are halogen alternatives out there that are fairly bright too, and I'm certainly not in any position to address the legal enforcement aspects of HIDs, I'm simply presenting the information I've found on the matter.
1 more thing, that "not very bright" guy in the end of the video is Edmund King, now the President of AA :D
