I remember when TiVO first came out I was all about TiVo. I came home and that thing was frozen, and I thought 'This is awful. This is the end of the world'. Then I unplugged it, and I plugged it back in, and still frozen. It was paralyzing. I called them. They said, 'Just unplug it longer.' Fixed.
