Tivo is fun, easy, and soo convenient. I am a 4 year Tivo subscriber and I don't think I could ever go back to a non-tivo existence. 

 DVR's in general are a great thing, but Tivo is extra special.  My favorite tivo function is the Wishlist.  I put in all of my favorite Actors in.  I also do wishlists for upcoming trip destinations,so I can find travel shows about places I will be visiting.  You can set it up to automatically record wishlist shows, or just save them and check to wishlist every few days.  Never miss your favorite actor or actress on a talk show, watch every travel special...
