Update panel and timer pausing video in WMP

I in a web form i need to display images as well as videos.For displaying images i have used a asp image control and using ajax update panel and timer i will be showing list of images
on regular interval of time.for displaying videos i am using object type windows media player and assigning a playlist to it.My problem is when image is being updated i.e timer tick event ,video is getting paused and resuming .

aspx code:

<asp:ScriptManager ID="ScriptManager1" runat="server">
<asp:UpdatePanel ID="BannerPanel" runat="server" UpdateMode="Conditional">


<asp:Image ID="Image1" runat="server" Height="360px" Width="425px" Visible="true" />

<asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="5000" >


<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />


<asp:Panel ID="Panel2" runat="server" Height="370px" Width="428px" CssClass="floatright">
<object id="VIDEO" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6"

style="position:absolute; top: 76px; left: 446px; height: 374px; width: 474px;" >

<param name ="playCount" value="999999999" />

code behind code:
protected void Timer1_Tick(object sender, EventArgs e)
NameValueCollection list = Session["ImagesLIst"] as NameValueCollection;
if(list != null)

IndexTmr= Convert.ToInt16(Session["tmrindex"]);

if (IndexTmr <= list.Count )

string ext = ".bmp";

string localstr = list[IndexTmr];
Byte[] bytes = File.ReadAllBytes(localstr);
string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);

Image1.ImageUrl = "data:image/" + ext + ";base64," + base64String;

IndexTmr = Convert.ToInt16(Session["tmrindex"]);

IndexTmr = IndexTmr + 1;
Session["tmrindex"] = IndexTmr;

IndexTmr = 1;
Session["tmrindex"] = IndexTmr;



protected void btnPlay_Click(object sender, EventArgs e)
