// this should be the first bit of code at the top of your
// actionscript for interactive video code.  this stuff needs to
// loaded and be ready for action before anything else
 
// import the necessary actionscript code for dealing

import fl.video.*; 
import fl.video.MetadataEvent;
// import the necessary actionscript code for dealing
// with metadata embedded in video [ie. cuepoints]

this code loads in the necessary actionscript classes for dealing with FLV [flash video] and metadata [in this case cuepoints].  this needs to be loaded right at the beginning of your code, so flash knows how to handle cuepoints embedded in FLV [flash video] files.

import necessary  actionscript to work with FLV  & metadata [ie. cuepoints]
