NetStream Video Control button issue

Question

The stop button plays as expected.  The play/pause button plays as expected.  The issue is when you press pause which will cause the play button to appear, then press stop.  the video automatically plays and it shouldn't. I have bolded the control button script for convenience.
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
theVideo.attachVideo(ns);
ns.play("LOB2_0644_new.flv");
stop_mc.onRelease = function(){
playpause_mc.gotoAndStop("playing");
ns.seek(0);
ns.pause();
playpause_mc.onRelease = function(){
ns.pause();
  if (this._currentframe == 1)
        this.gotoAndStop("playing");
        movie_mc.play();
    else
        this.gotoAndStop("paused");
        movie_mc.stop();
    } // end else if
} // End of the function
var videoInterval = setInterval(videoStatus,100);
var amountLoaded:Number;
var duration:Number;
ns["onMetaData"] = function(obj){
duration = obj.duration;
function videoStatus(){
amountLoaded = ns.bytesLoaded / ns.bytesTotal;
loader.loadbar._width = amountLoaded * 424;
loader.scrub._x = ns.time / duration * 424;
var scrubInterval;
loader.scrub.onPress = function(){
clearInterval(videoInterval);
scrubInterval = setInterval(scrubit,10);
this.startDrag(false,0,this._y,424,this._y);
loader.scrub.onRelease = loader.scrub.onReleaseOutside = function(){
clearInterval(scrubInterval);
videoInterval = setInterval(videoStatus,100);
this.stopDrag();
function scrubit(){
ns.seek(Math.floor((loader.scrub._x/424)*duration));
_root.createEmptyMovieClip("vSound",_root.getNextHighestDepth());
vSound.attachAudio(ns);
var so:Sound = new Sound(vSound);
so.setVolume(100);

Answer 1

before executing gotoAndStop("playing") check if playpause_mc is already on the "playing" frame.   if it is, do nothing.  if it's not, execute your gotoAndStop().
also, you probably want:
   else
ns.play();
        this.gotoAndStop("paused");
        movie_mc.stop();
    } // end else if
