I have two Tivos and know which one I want to get upgraded. I can't use the online upgrade link it leads to a generic VM HTTP 500 error when clicking on the "let's go" button on
https://store.virginmedia.com/existi.../v6eligibility. So will take the phone route to request the update.
What piece or pieces of information will be required to identify the correct Tivo? I want to have this ready when I call.
