The THR22 started rebooting on its own at 6:30 PM last night (11/!9/13). It did 5-6 reboots in quick succession, then worked OK for 30 minutes before rebooting again. It continued like that the rest of the night. We've had the THR22 for about 4 months. I know that, last year, in November, the SD DirecTV TiVo had similar problems. I thought this might be a variation on that, and checked here and at the DirecTV and TiVo forums, but no one else has asked about this. I called DirecTV, and was told by the first rep that the THR22 would most likely have to be replaced. When I asked to be transferred to a TiVo specialist, or Engineering, I was told she could only let me speak to her supervisor. I was put on hold for so long that I hung up. I called later last night, and the rep this time said that this was a known issue with the THR22, an issue they'd been aware of for the last 3 weeks. Anyone else have this problem? Any suggestions other than waiting for DirecTV to fix this?
