Our TiVO box seems to shut itself down every now and then. It usually does it whilst we're out at work so I have to press the power button and then watch the "starting up" screen for five minutes. It's also just shut itself down now. I've adjusted the power options so it shouldn't go to sleep or anything but it's not made any difference.
torchomatic its funny you should mention that sometimes mine did that woke up 1 morning its fine then next day red button on standbuy it does do that if you have gone in to sleep mode settings check that then it shouldnt do it but if it still does it then 150 or get back on here and team will investigate further jonni
