Разобрался.
Вот мой ответ был в английский форум:
I found the answer in examples which are in FMS folder.
There is "Buffer" example.
The following works:
I created the folder .../applications/myProgram.
I placed FLV files to
.../applications/myProgram/streams/_definst_
The code is below:

Код:
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
nc.connect("rtmp://localhost/MyProgram");
...
private function onNetStatus(event:NetStatusEvent):void {
case "NetConnection.Connect.Success":
ns = new NetStream(nc);
ns.client = this;
ns.play ("myFlvFile"); //I don't write ".flv" here
vid = new Video(320, 240);
vid.attachNetStream(ns);
addChild(vid);
Хрен знает почему надо писать файлы в streams/_definst_
----------------
As for playing FLV files from HTTP server.

It seems the all file is downloading before playing.
That causes delay.
Bad solution in Flash player. But I don't know how to avoid that.
Thanks.
