understanding the buffer

hello;

anyone know of a good resource to get the abc's of stream buffering?

I don't really get what a buffer is for, what it holds, why it is holding it, who needs it ( the server or the user's computer ), is an empty buffer good or is a full buffer good, etc/



I seem to be getting NetStream.Play.Stop events even while the flv is playing, and it seems that buffer has something to do with it;


thanks
