Skipping through video like YouTube, before the whole thing has loaded?

Hey guys,

Been a while since I have used flash, but I finally have a chance to get my hands dirty again. I’m putting together a video player and all it’s all working fine so far.

I was wondering how you can add similar functionality to the player like YouTube, where you can skip to any part of the video before the entire flv has downloaded?

Any info on the subject is appreciated.
