We bought a pair of refurbished TiVoHD boxes back in August to go with our new FiOS install, one for the living room and one for the bedroom. All was good until a couple weeks ago... The bedroom TiVo developed a problem where any operation other than watching live TV would take 100x more time than normal. You could press the Now Showing button and go have a quick snack before the list of shows would form. Same with any operation in TiVo Central - press the button and wait. So I called TiVo and got an advance exchange headed our way, all nice and under warranty except for the $50 labor/handling charge and the $320 refundable deposit for the new TiVo. It arrived a few days later, I hooked it up, and it failed after an hour of use. This new unit reboots itself every few minutes. So I called TiVo again and got yet another exchange headed our way along with another $320 advance exchange deposit on the credit card. It arrived yesterday, and it's exhibiting the same problem as TiVo #2 except sometimes instead of rebooting itself, it'll just hang on startup and not do anything at all. So I called TiVo yet again. We discussed possible environmental issues with the box, I dragged out power conditioning surge protectors and extension cords and plugged it in dozens of times over the whole house trying to find something that would make it work. No luck. One last call to TiVo this morning has replacement #3 headed my way with an accompanying (you guessed it) $320 deposit. TiVo numbers 1 and 2 are on their way back to the mothership and we're looking at another few days with no TV in the bedroom. I did a quick search, but don't see where anyone else has had this kind of hardware trouble. If anyone has any insight, please do share, and in the meantime, thanks for letting me unload my story here. Hopefully we've just had a patch of bad luck and the next TiVo will be fine!
