Update to this: I was able to get pvrupgrade to authorize another download, and this one worked - however, I now cannot get past setup guide on Tivo... My newly upgraded Tivo will not recognize my Tivo wireless adapter. I have tried using phone line (Vonage, so not sure it will work - but haven't got that far), but Tivo reboots during the 'Preparing' stage. Sometimes, it does recognize that I have a wireless adapter, but does not see any networks, and prompts me to enter in the SSID and password - which I do. I then get an 'unrecoverable N19 error' which tells me to pull the power and start over. So, I cannot connect via phone, and cannot connect via wireless. Before I go the PPP route, does anyone agree with me that there is something more seriously wrong with this machine???
