Advertisements I had an S2 DT for three years before switching to my HD. AFAIK the S2 was functioning perfectly when I shelved it. However about 2 or 3 times per year the S2 would just spontaneously reboot -- no relation to what it was doing at the time. No major problem -- didn't get worse -- so I just chalked it up to the nature of the beast. Given the presumed complexity of TiVo software, the need for an occasional reboot would not surprise me. I just had my first spontaneous reboot on my HD, which seems to be functioning fine both before and after the reboot. I've had the HD for 4 months. Some detail: I have a Tuning Adapter, Digital Cable, and use HDMI to the TV. I had just tuned to the local ABC affiliate station, which was playing fine. I clicked the remote info button and got no response. I tried other remote buttons, all with no response, although I noticed the amber light was responding. I decided to just wait a while to see if it cleared but after maybe 45 secs the TiVo rebooted. There is another problem I've had occasionally. I would lose remote response at apparently random times. But this problem is different because the amber light was not responding. In all these cases either just waiting a while or power cycling the TV (not the TiVo) would regain the remote response and a TiVo reboot was not required. Thus I attributed this to an HDMI handshaking glitch. This problem has simple workarounds and doesn't occur often, so I live with it. Hasn't even been worth trying component connection to TV to see if it goes away. So I'm wondering if occasional spontaneous reboots are normal ?
