How can I have keyframes on one layer proceed while using the gotoAndStop function?

Question

I have a Flash presentation that allows me to pair videos with the slides using a nice piece of ActionScript. The presentation advances to the slide on the next keyfram when the viweer clicks the "next button" and the video for that keyframe (on a separate layer) begins playing.
owever, I am now trying to pair two slides with the same video without having the video restart or requiring the viewer to click the"next slide button" I was hoping I could just turn the two slides into a video clip, convert it into a symbol and insert the symbol in place of the static slide, but nothing seems to happen. I'm wondering if the "gotoAndStop" function in the ActionScript is preventing it from playing.
Any thoughts on how I can have the presentation be controlled by the next and previous buttons most of the time, but have the exception of one slide that changes on its own? The relevant (I believe) code is below.
Thanks!

Try this code. Replace FLVmovie with the instance name of your FLV & set the time to when the frames shoudshould advance.
import flash.events.Event;
this.addEventListener(Event.ENTER_FRAME, checkTime);
function checkTime(e:Event):void {
      if (this.FLVmovie.playheadTime >= 15)  // This is the playhead time in seconds
          this.gotoAndStop("frame label or frame #");
          this.removeEventListener(Event.ENTER_FRAME, checkTime);
