This one has me stumped. All of a sudden, whenever I would turn on my AV Receiver, the TiVo-HD would power cycle. What's very odd, is that the receiver is plugged into a surge protector, then into one outlet; while the TiVo is plugged into a APS UPS box (about two yrs old-along with the tuning adapter and the TV), and the UPS is plugged into a different set of outlets (though likely on the same circuit). When I would hit the power button on the remote, the receiver lights up immediately as it normally does, and at the same time the UPS lets out a single beep, and the TiVo goes through the power up cycle. Perhaps a dead battery in the UPS, or I need a new UPS. Or perhaps even the receiver remote (default Pioneer, as opposed to a Harmony) is inadvertantly sending a power cycle code to the TiVo?? This started a few weeks ago, and nothing in the rack has been changed.
