popup div containing embedded media player [duplicate]

This question is an exact duplicate of:

• On close of a video div, video closes but sound does not stop

I am showing a popup within a div having unique ID and I placed a Close button on that div, on hitting of that button, div is hidden and hence player is made stop. This is working properly with mp4 format, but when I am going to play wmv format then div is being hidden but sound keeps on going until it reaches to end time.

please help me... I will be thankful to You.

js is being given below..

function loadMovie(mediaLink, mediaTitle) {
var playerHtml = "<div id='playerContainer' class='playerContainer'>";
playerHtml += "<div class='player'>" + GetPlayerTag(mediaLink) + "</div>";
playerHtml += "</div>";
$("#playerDiv").empty().append(playerHtml);
$("#playerDiv").dialog({
    autoOpen: false, title: mediaTitle, modal: true,
    width: 550, height: 400, closeOnEscape: false, modal: true, resizable: false,
    show: {
        effect: "fade",
        duration: 1000
    },
    hide: {
        effect: "fade",
        duration: 1000
    },
    create: function (event, ui) {
        var widget = $(this).dialog("widget");
        $(".ui-dialog-titlebar-close span", widget).removeClass("ui-icon-closethick").addClass("ui-icon-DialogCloseButton");
    },
