Convert AS2 to AS3.

This script is from the livedocs site.  Any help getting this to work as AS3 would be greatly appreciated.

import mx.video.FLVPlayback;
var my_flvPb:FLVPlayback;
my_flvPb.autoPlay = false;
my_button.label = "Seek to point2";

function clickMe(){
  my_flvPb.seekToNavCuePoint("point2");
}
my_button.addEventListener("click", clickMe);
