Looking to upgrade to Tivo Desktop Plus. When I got to buy it, it seems like the only option is to have it shipped to my physical mail address. Is there no download option? I am wondering if perhaps they just have a clumsy/inaccurate checkout process and when I get to the end it's going to E-Mail me a download key. However, I don't want to finalize my purchase and I find out I truly have to wait 3-5 days for a CD to be mailed to me with the software. Anyone have any experience with this process?
