Add me to the Seattle-based folks with Series 1 dialup issues. My SVR symptoms are the same as monkeyfacedave and dotcomcto's, and they started to happen around the same time, early December. Test calls are successful, local numbers are updated via the dialup connection, but always fails at the same point when connecting to get program data. On-screen display shows the normal sequece of dialing -> answering -> connecting, and it's always after the 'connecting' status that the dreaded 'Failed. Service Unavailable' message occurs. Behaves very consistently across every local number and every dial attempt. No changes in my phone service, physical configuration, anything, in years. Customer support folks confirm that server logs show the connections being made, but no other information or error codes were available to the first support rep I talked to(who was the most helpful of all I've spoken with thus far). They escalated my ticket, said it would be looked into in the next few days, that was almost 2 weeks ago. My suspicion is there was a software update that happened around that time that broke legacy Series 1 functionality. I also got the same runaround about Verizon digital technology 'frying my modem' as the root cause - baloney. To add to the internal/external modem data points, I'm still using the internal modem. I have lifetime service and am very unhappy with the curent state of Tivo's response on this issue. If anyone gets any traction towards the root of this, I'd be most grateful to hear.
