simultanious playback issue

Here is my problem:
I have 2 (or more) instances of the same SWF file, and each one runs on a browser window or tab.
A message is sent to all the instances to play the same video. The FLV files are hosted on a web server (so no FMS is involved here).
The first instance to play the movie calls the onStatus function (called when the video state changes) almost immediately after the play() method is executed, but the problem is that, unlike the just mentioned behavior, the other instances take a long while between the execution of the play() method and calling the onStatus function, causing the video to start playing several seconds (even minutes!!) after calling the play() method.

Does any one know what's happening here and how it can be solved?

HERE IS CHUNK OF CODE JUST FOR ILLUSTRATION PURPOSES:

rcn.call("initVideo", null); //sends a message to all clients to execute the initVideo() function

function initVideo(){
     videoStream.play(flvFile);
     var currTime = (new Date).getTime();
}

function onStatus(info){  //executed when the video state is updated
     var elapsedTime = (new Date).getTime() - currTime;
     trace ("Instance " + instanceNumber + ": " + elapsedTime + " seconds elapsed"); //Shows the elapsed time between the execution of play() method and the execution of this method
}

Flash tracer output:
Instance 1: 2.212 seconds elapsed
Instance 2: 40.212 seconds elapsed
Instance 3: 40.831 seconds elapsed
