Advertisements Wanted to send this alert out to everyone. My Series 3 has become unresponsive: Hangs at menus, reboots itself, unable to watch HD I called TIVO and told them it happened right after a software update. They admitted that the software update has caused problems with some Series 3. DON'T LET THEM TELL YOU IT WAS A HARDWARE FAILURE. My unit is less than 6 months old and worked PERFECTLY only 3 days ago. They've had to exchange many series 3 for people. I hope this information has helped.
