Hi:
You can just change this <object> tag to <asp:Literal ID="Literal1" runat="server".....>. In Repeater_ItemDataBound event handler, assign this to the text of literal:
DataRowView drv = (DataRowView)e.Item.DataItem;
Literal l=(Literal)e.Item.FindControl("Literal1");
l.Text="<object type="application/x-shockwave-flash........" + drv["DataField_in_Your_DataBase"].ToString() + "..........</object>";
If it doesn't work, please inform us.
Regards
