I really do not know much about the Xbox and I am debating between an Xbox and PS2 premod. Soemthing that would make my decision easier would be to understand better: 1 - Can they read dvd +r media? 2 - Why is it better to have a larger hdd? 3 - How effective is the Xecuter Lite 2.2 chip? 4 - And last, How easy is it to play backed-up games (does the chip constantly need to be flashed?)? Any help is greatly appreciated. Thanks.
