Advertisements Yesterday I was watching a live HD program (a FOX NFL game between the Niners and Seahawks, but I doubt that matters) and my TiVo S3 surprisingly rebooted (maybe I should thank it considering that game was soooo boring since I'm a fan of neither team). It was the first time this happened to me and in the event that this re-occurs is there something I should be looking at that might indicate the cause? When my TiVo rebooted several minutes later I didn't see any new system messages so I'm not sure where I would be able to find any information. The only thing I noticed, the amber and blue lights on the OLED remained illuminated for about a minute, then the blue light(s) disappeared and finally the amber a few moments later. I searched this forum and only located threads of people having constant/frequent reboots-- so I don't think those would provide much info on a possible one-time reboot. Since this was the first time my TiVo self-rebooted (w/ the exception of when an update is downloaded and installed) I'm curious as to what might be the cause but also how one tracks down the cause after-the-fact. FWIW, my TiVo is connected to a UPS (along w/ my TV and receiver which neither of those power-cycled at the same time) so I don't think a power spike/loss was the culprit.
