I am having the same problem. Since 12/2, out of the blue my Series 1 stand alone will call start downloading and then Failed - Call interupted after 10 minutes. I actually have an external modem because my internal modem was fried by a summer electrical storm years ago. Test calls work just fine. I have changed the call in number 4 times (Minneapolis 612 area code). Every time - dial tone, dailing heard, connection heard, verifies account, set clock, downloading then after 10 minutes Failed Call interupted. There are enough people this is happening to that it is not my machine. It is how the series 1 is accepting the download info. I have another Tivo (different Series) in the household that has not had a problem with the same dial in number.
