Would you say all of them are in house? I've noticed (sorry I HAVE visited them) a site might have full clip after full clip, but then will feature a ton of brief (but well edited) clips of a big site. It's pretty obvious that that company is a least in bed with them.

Again, maybe I wouldn't have looked if it weren't so goddamn easy. I first found a bunch of them while reading an article about 'em on LiB. He named the sites and had links to all of them. Duh....
