When I play a movie in my DVD-Rom Drive (E), Showtime 3 works perfectly, but if I play it in my DVD Writer (D) it plays any introduction etc. but instead of playing the movie itself, displays the error "Playback is impossible because CSS copy protection failed". The movies are all legitimate DVD's and not copies. Windows Media Player 10 plays the movies in both drives ok. Can anyone help with a possible cause? I would prefer to use my (D) drive because it is whisper quiet, whereas the (E) drive is much noisier. Thanks for any ideas.
