Icon pops on video playback or causes whole movie to play at once

programming flash
1

Hello all.
I’ve just converted a Powerpoint presentation to Flash. Several slides/frames have video on them, so I’ve got a FLV in those frames with the video, as well as the controls for them (which created a video controls swf upon publish). The videos themselves are in an FLV subfolder of the final swf.

When I finished, I zipped up the final swf, the controls swf, the generated html with the swf inside it, and the FLV folder. I sent it to the client.

She has written back to say that she opened the HTML in IE and got to the first slide with video. She said she gets a little icon in the upper left corner of her screen that says FLV in red letters, and it blinks. She said it gives her a little icon that looks kind of like a 2-slide handout.
She then tried to open the HTML in FF. There, she can see the controls on the video, but when she presses play, the entire Flash movie zips through all subsequent frames really quick.

I have no idea what is causing this or how to remedy it. I unzipped the contents to my own hard drive in a new folder and it worked for me. I even tried it on my girlfriend’s separate computer and it worked there.

For the sake of technical questions that may be asked:
I used Flash CS4 w/ AS3. Client says she has most recent version of Flash and its players.
The Flash doc is set up with two layers. One is called “bg” and each frame is one slide. The other layer above it is called “actions” and the first frame has the following code:

stop();

import flash.ui.Keyboard;
import flash.events.KeyboardEvent;

this.stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler); 
function keyDownHandler(event:KeyboardEvent)  : void
{
    if (event.keyCode == Keyboard.RIGHT)
    {
        nextFrame()
    }
        if (event.keyCode == Keyboard.LEFT)
    {
        prevFrame()
    }
}

This extends the length of the “bg” layer.

Each frame on “bg” is just a bitmap, unless animations or video occur on that frame. In that case, I converted that frame’s bitmap to a movie clip. Inside, I create the animations w/ tweens, and/or video players. There’s an actions layer atop all of this in each movie clip, where the final frame has the stop(); command

Anyone have any ideas what the problem is and how to correct it?

Thank you!
