How to mute FLVPlayback on default?

I'm using the default flv player component in Flash cs4. I want my video to start on page load, but I would like it to be muted in the beginning, so the visitors can chose to unmute it if they want.

I tried to google and found a number of solutions which doesn't work for me(or rather I don't know how to make it work).

There seems to be a good solution here: http://bangersandflash.net/muting-flvplayback-component-by-default/

But the zip link is broken, and I'm not sure how to piece the tuto开发者_运维技巧rial together.

Is someone able to help me shed some light into this situation by providing me an example fla file?

Edit: I tried something like this but unfortunately it didn't seem to work:

myVideo.volume = 0;

myVideo.muteButton.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(e:MouseEvent) {
    myVideo.volume = 1;
}

var flag:Boolean;
foo.volume = 0;
foo.addEventListener(MouseEvent.CLICK, action);
function action (e:MouseEvent):void 
{
    if(!flag){
            foo.volume = 1;
            flag = true;
        }else{
            foo.volume =0;
            flag = false;
        }       
}

if you want to keep the functionality of the player skin, use this:

mc_video.volume=0;
mc_video._uiMgr._isMuted = true;

am aware this is an old question, but someone might still need this answer.
