My siblings and I JUST purchased a Tivo Series 2 for my folks... The dual cable tuners would have come in handy since they have digital cable and the digital converter boxes make it difficult to watch one thing and record another if both programs are on digital channels.
If it's been less than 30 days you can send it back no questions asked. However, you will be waiting far longer than 30 days for this "series 3" box to appear on store shelves. It if was ready to go it would have been out there for the end-of-year-madness shopping season. -- Toolmaster of La Grange.
