I burned a backup from my copy of PDS w/ the program listed in the FAQS (CDRWIN), and although the other games I've made copies of work flawlessly, PDS seems to have quite a bit of trouble. First of all, I am only able to get it to start by using the single-swap method. This is a problem exclusive to this game. Second, when I am able to get it to work with the disc swap, the game randomly returns to the CD player menu. This occurs during play, not after the intro movie. Anyone know what could be causing this? I'd like to use the original discs as little as possible.
