I have a Tivo with a failed motherboard. I replaced it, and I was hoping I could watch my shows that I had recorded before it broke. It powers on fine, but when I get to the now playing list, it says "hardware failure detected" and to restart the tivo. From what I understand, the Tivo will work fine if I erase the hard drive. But, that defeats the purpose of trying to save the programs. I just read that tivos use an encryption chip on the motherboard, and I am horrible at soldering. Are there any other options?
