Three times over the last couple of weeks I've hit the TiVo button on my remote only to have "Welcome Powering Up" display. The TiVo then boots and all is well. I don't think it is hung because the case is stone cold. The only other symptom is that once it boots I get the grey screen with the "press the Tivo button" message rather than just going straight into the TiVo startup movie. I do usually sleep it using Messages & Settings->Standby. Could this be the sign of a bad HD or bad power supply or is it more likely a software issue related to my use of "Standby"? I might run the HD test and I'll probably not use the standby button (I use that to keep the Tivo from putting sound through my stereo should I forget to turn that off) and see if either of those help. Any other ideas?
