"I had purchased a lifetime TiVo subscription many years back (2003, I think). About two months ago (May 2011), my TiVo stopped working. It was stuck on "Powering Up". I searched for solutions on the internet, and found www.dvrupgrade.com. I was hesitant, but thought I would give it a shot. It was your guarantee that finally convinced me.
Just a few days later, and I can't believe that I was able to change out the hard drive myself, and keep my lifetime TiVo subscription."
