After installing XP in my system I have a problem playing DVDs. Programs or system tell me that there\'s a problem with the author copyright of the DVD so it won\'t play. The problem tell me that the TV out option of the gforce 2 is activated... the dvd thinks that i\'m gonna copy it and then stops the play. I\'ve looked for the option bur I don\'t know how to desactivate this tv out option. I have not secondary monitor, or anything similar. And yes, DVDs are totally authentic.
