I'm a new TiVo adoptee and purchased two Premiere XL4's with lifetime service. That said, I'm having intermittent soft reboots sometimes as often as once/day on my family room Premiere and only a few times on my master bedroom Premiere (which is used a lot less). It never happens while simply watching live/recorded TV, but only when I'm interacting with it. I use the TiVo iPad app most of the time versus the remote (not sure if this has anything to do with it) and today I hit the TiVo button and heard the ding but the TiVo never opened up the page so I hit it again and all of the tuner lights illuminated briefly and the unit restarted unexpectedly and then I saw "Welcome, Starting Up..." Because both of my Premiere's have done this I'm hard pressed to believe it's a double hardware fault. Again, this only seems to happen when I interact with the TiVo. Tech support could only tell me that TiVo's will reboot to protect themselves - not sure from what in this case... My signal levels are perfect and both TiVo's are hardwired over gigabit with plenty of air ventilation and nothing above or below them. I'm hoping that TiVo keeps some sort of event logs which tech support could analyze. Anyone else seen this kind of behavior?
