I had made a project & when I tried to preview it the first screen that I saw wasn't the media I wished. I eventually realized that I had to set the 'DVD start' , the one with the little purple asterik. Then it previewed corrctly on my PC. I burned a copy but both DVD players that I have tried it out on still won't play the selected screen first as I had wished. Any ideas as to how to fix the problem? The media in question wasn't introduced as introductory media., does this matter or not?
