This is as of late 2006 something of a history lesson. TiVo has managed to stay independent (at one point it was DirecTV's only DVR). TiVo records shows as typed in by the user whether by program title or keyword (such as Buckeye football). The viewer is given a choice of video quality (the higher the quality, the more space it takes on the hard drive). If the show is a series, the user can record up to 5 episodes and even keep them if she wants (right on the TiVo or "offload" them onto a VCR).
It's getting close to calling it a day, but there are a number of screen shots as well as pictures of the TiVo remote at http://www.humaxusa.com/image_gallery.html as of 21 November 2006.
