Just set AppendDataBoundItems property to true on your dropdownlist. Then add a new list item in your aspx code like

 <asp:DropDownList ID="ddlInstallTypes" runat="server" 
            DataSourceID="odsTreatyInstallTypes" DataTextField="DisplayText" AppendDataBoundItems="true"
            DataValueField="Value"> <asp:ListItem Text="- Select -" Value="0"></asp:ListItem>
        </asp:DropDownList>

This way a new list item will be added to the list on top.

You are probably trying to insert new value at zero index of dropdown items, you need to use Dropdownlist1.Items.Insert to add element at the first location. 

Dropdownlist1.DataSource = Movies;
Dropdownlist1.DataBind();
Dropdownlist1.Items.Insert(0, new ListItem("Choose one", "Choose one"));
