Advertisements So lately my TivoHD has started acting flakey. 1) Recordings are truncated. 2) Last night i was watching live TV and the picture froze. It would rewind and play, but wouldn't go past that image. When I switched channels and came back, all was good 3) Occasional reboots, maybe once a week, but they seem to be getting more frequent. I'm assuming my hard drive is going south, as the unit is several years old. Should I replace the HD? or get a refurb one? (I don't have lifetime, so I don't know if that matters). I also assume its not under warranty.
