I just received my Directv Tivo receiver. I would like to add this receiver to my Tivo Desktop and it is asking me to enter the TSN (Tivo Service Number) in order to add it. How do I get this number? Tivo Desktop allows transfer of Tivo recorded programs between Tivo recorders. When I go into the Desktop it shows a new Tivo (identified by DVR-A403), but it is not the TSN number that I need. So, it is recognizing that there is a recorder there but I cannot transfer anything from that number when I highlight it. Any help you can provide will be greatly appreciated!!!!
