Okay, I know you have a love/hate relationship with BtVS, but Paper Cup (http://www.heresluck.net./videos.html) has some brilliant ones--by heresluck. Atropine is particularly good.

One of my all-time favorite videos is Transparent by Laura Shapiro--you can find it , though you have to email for a pass. It's worth it, and watching all of her vids are wonderful.

I'm partial to Istanbul (not Constantinople) (http://www.livejournal.com/users/dsreporter/276224.html) by Alasen in the due South fandom; short but funny. Closer (http://www.headtilt.com/video.htm) by sisabet is one of the best AtS videos of All Time. Gah. So hot.

And if I can persuade you to slip into a new fandom (c'mon, it's good for you) shalott's (http://www.intimations.org/vidding/) Smallville vids Drop Dead Gorgeous is a classic favorite. I also particularly like her Jig of Life, Touch Me Fall, and Behind Blue Eyes (Witchblade, XMM, and BtVS). But of course, most things shalott does are great.

rivkat also has some good Smallville (http://www.rivkat.com/vids.html) videos. You need to get into this fandom, man. Let me show you the light.

I'm sure there are more, but I'm not using my own computer so I don't really have links. This should start you off though. (http://www.laurasha.com/)
