I have two TiVo units, and this morning one of them seemed to have rebooted and gets stuck while booting up. I make it to the "Just a few minutes more" orange screen, but it stays there (I left it up all day to see and that's still the case). I've disconnected and reconnected the power, and still the same thing. I've had my TiVos for years; I love them and they have been very good to me without any problems until today. Anyone have any suggestions as to what I should do? The unit in question is a Series 2 TiVos (240-0000-XXXX-FXXX). HELP!
