回答1:

I would do this differently.

Personally, I'd not embed the video as this is the problem! Instead, embed a picture of the video or similar, the onclick then loads the appropriate video in a new window.

Update your template too

<ItemTemplate>
             Description:
             <asp:Label ID="DescriptionLabel" runat="server" 
                 Text='<%# Eval("Description") %>' />
             <br />
         <a href="wherever" javacriptCommandToOpenPopUpHere><img src="picture.jpg"></a>
<br /><br />
</ItemTemplate>

You may also need to update your Insert command as it may allow for SQL injection.
