How to resolve "Movie not loaded..." error in asp.net web application?

[Napsterr]

Hi,
I have asp.net web application in which I am trying to show a youtube video. I have stored youtube url in database.
I am using a repeater control as I wanna show multiple videos at a time.

But, when page loads, it doesn't load video. After right clicking on page it shows 'Movie not loaded...'
How to resolve this?

Following is the code I am using.

<asp:Repeater runat="server" ID="rptrVideos">
<ItemTemplate>
<table>
<tr>
  <td>
   <object width='640' height='385'>          
     <param name='allowFullScreen' value='true'></param>
     <param name='allowscriptaccess' value='always'></param>
     <embed src='<%# Eval("VideoUrl")%>' type='application/x-shockwave-flash' allowscriptaccess='always'              allowfullscreen='true' width='139' height='190'>
    </embed>
   </object>
 </td>
</tr>
</table>
</ItemTemplate>
</asp:Repeater>

Please help me...
Thanks in advance.
