Ok, I'll back up. Just over a year ago I sent in my Tivo for a replacement, after everything I tried to do to revive the Tivo failed. This is that thread: http://www.tivocommunity.com/tivo-vb/showthread.php?t=454566 I upgraded the hard drive with the 1TB EARS in January. It worked fine for a while then started rebooting in April. Eventually I cleared it off and sent the hard drive in for a warranty replacement. Now, the replacement hard drive, which I installed in July is displaying the same behavior.
