President Bush has signed legislation aimed at helping parents shield their kids from sex, violence and foul language on movie DVD's.
The measure gives legal protections to emerging technology that allows the automatic skipping or muting of scenes in commercial movie discs.
The White House says the president signed it privately and without comment.
The legislation was a response to legal action by Hollywood studios and directors to stop the sale of filtering technology. They argued tampering with content violates copyright laws. The bill that Bush signed creates a copyright exemption.
Critics of the bill have argued it's aimed at helping one company, Utah-based ClearPlay Incorporated, whose technology is used in some DVD players.
