I have a 14 year old son, and he, my wife and I share our TV and Tivo. While we are certainly not prudish about what he watches (PG 13 movies, TV 14 shows, and some of the more sophisticated animated shows such as Family Guy), there are shows on our TV, mostly through HBO and Showtime, such as Real Sex, or Entourage to name two, that we don't want him to watch. I am surprised that a system as sophisticated as Tivo doesn't simply have a way of blocking individual shows. It seems it would be easy to put a menu button within the menu of each show that allows one to lock it, and to be able to open it up with a password or PIN code... I know that Tivo has Tivo Kids Zone, and that makes a lot of sense for kids. For early teens, however, it's a bit limiting. So I am wondering if anyone knows a way to do what I am wanting to do. If not, how can I make sure that the developers of Tivo see this recommendation? Any response will be welcome. Thank you.
