DVD Player Limitations
DVD Player complies with most copyright laws, and will thus enforce most restrictive measures of DVD technology, such as region-restrictive encodings and user-inhibited operations (“disabled actions”). It will even force Apple’s Grab (screen-grabbing) program to cease functioning through the Finder interface until the DVD Player application is quit, effectively preventing the user from taking screen captures of visual DVD content (It can indirectly be done by using a Terminal command. Video capture, of course, can be done with other programs, such as the VLC media player. Additionally, DVD restrictions can also be removed with decrypting software such as MacTheRipper).
