What region is this dvd. My xbox hasnt been working so ive ben using my ps2 and it wouldnt play my stewie dvd. But then i tryed all my other dvds and it played them. But my ps2 still gave me a dics read error. The condition of the disc is good there is no scratches or anything wrong with it. Any body know whats wrong? I checked the box of the dvd and doesnt stated a region.
