exact same thing. The dvr my kids use has the smallest hd, so I record some shows for them on my 750GB tivo. To mrv anything to it requires the parental code. I don't want their tivo to go without parental controls, nor do I want to unlock it for them and forget to relock it. My wife and I have some shows on the bedroom tivo that are not for their viewing.
I can find no other threads with this info.
