My Tivo HD, with 1T Expander, reboots itself 2 or 3 times a day. It started about a month ago. Had the unit for couple of years without problem. Tried to get into the Kickstart menu but pressing and holding pause at boot doesn't get me there so I can't run the test. Hate to have to call support and spend an hour doing all the things I've done ten times over. I have the extended warranty so I should be covered, just a pain. Ideas? Tony.
