Currious to hear what anyone has to say with respect to playing DVD games on the entertainment system. A number of different dealers have mentioned to me that "you can even play games" on the DVD system. Is this possible? If so, what equipment would it require and how does it work? Not having ever had or even played anything like Playstation or Nintendo's Game Cube, I do not have a clue how - or even whether - this might work. Appreciate any "starters" advice.
