There are three ways of viewing I;ve tried... one is the in-place plugin method, another is the MS media player, and the third is InterVU, a free player.
The in-place loads the whole clip before doing anything. The MS player tries to stream, but get's out of sync easily. the InterVU player streams so that you see things coming along until it's all there. On a real connection (vs. Modem) the latter two allow almost instant viewing like Grego says. Once they are downloaded, the play button allows viewing as it was meant to be (over and over)
I found the InterVU player to be the most pleasant to use. There are probably more out there...
Anyway, I will put up a few more choice clips in the AM. Also, look for tips and techniques with attitude in the near future.
