Flash loadMovie with embedded FLV problem...HELP!

[font=Century Gothic]I have a problem with my flash movie and it is the following if anyone can help me. First of all I have a container flash movie that pulls and xml list of movie names and locations and lists them on that movie (main movie). For now I just have two .swf being loaded to that main movie. The problem is that on in one of those .swf files I am loading an external .flv video and it is playing back perfectly when I initially load that movie for the first time. The problem is that when I load a different .swf and then load that .swf with then .flv in it the a time_interval text field that I have set up that displays the time is not seemless (meaning seconds are displayed like 1, 0, 2, 0, 3, 0, 4, 0, 5, 0, etc.)

Here is the code that calls the .swf from the main move:
//plays clicked movie
this.pageMove = function(url) {

loadMovieNum(url, 1);


//This is the .swf with the .flv in it
var nc:NetConnection = new NetConnection();
var ns:NetStream = new NetStream(nc);
ns.play(“giovanni.flv”); //place the movie name you want to use

//time text
this.createTextField(“time_txt”, this.getNextHighestDepth(), 345, 300, 100, 22);
var time_interval:Number = setInterval(checkTime, 1000, ns);
function checkTime(ns:NetStream){
var ns_seconds:Number = ns.time;
var minutes:Number = Math.floor(ns_seconds / 60);
var hours:Number = Math.floor(minutes / 60);
var seconds = Math.floor(ns_seconds % 60);
if (seconds<10){
seconds = “0”+seconds;
time_txt.text = hours+":"+minutes+":"+seconds;

//there are some playback controls under here

Can someone help me!
