Ah, mine is much different there is a single code, and you must enter it to access any parental control functions. If I wanted to add a new channel or a single movie for example, I would have to enter that code.
Why would you need to keep the code from YOURSELF? I mean, I can understand keeping it from your children, or your wife if she's getting some kooky liberal ideas, but why the cover-your-eyes/have-a-neighbor-do-it approach? Are you so afraid of your own weakness that you have to "trick" yourself? Not a good sign for the conservative movement.
