Advertisements I purchased my S3 in May of last year. It's worked perfectly for 14 months and then last Monday (July 14th) it started rebooting every 10 minutes or so, consistently. I called tech support and they said I had a defective unit and I needed to exchange it. Since it was out of warranty, they charged me $149 for a replacement (which is a lot nicer than buying new). The RMA center is just a few hours up the road, so I shipped the "defective" TiVo on Wednesday, they received it on Thursday and shipped me back a refurbished unit, which I received on Friday. I was pleasantly surprised by the quick turnaround, but when I opened it, it looked like the TiVo has been dropped as the front was all bashed in. I didn't even bother hooking it up. When I called to complain, they apologized and said they would replace it with a brand new unit. So I shipped off the broken refurb on Monday and received a brand new unit today. I hooked it up and it doesn't even get past the "Welcome! Powering up..." screen before it reboots. I let it go through the reboot cycle 8-10 times and then called tech support again and all their computers were down (and still were as of 15 minutes ago) so they couldn't help me. But the technician did say that I will probably have to ship this one back too as they are having "a lot of problems with the series 3 boxes" and tried to talk me into swapping it out for their standard HD unit. Lame. What's going on? I do not have CableCARDs. I have tried disconnecting the coax (that goes to an OTA HD antenna), the HDMI, and the WiFi adapter, but it's still rebooting over and over again. I don't know what software is on this new unit (because it never fully boots), but the original one that worked fine for 14 months and then started rebooting every 10 minutes was running version 9.3a-01-2-648.
