[quote][b]Posted by:[/b] Burn Your Dad I just found a problem. The xbox customer support line just told me some imported discs are unreliable, because they could be coded differently depending on thier location. My location is Puerto Rico. Everyone should post where thier discs come from to make sure we can rule out coding problems.[/quote] Already discussed, and 90% of all discs were made in either Mexico or Puerto Rico. Supposedly, it has little to nothing to deal with the Disc Unreadable Error. [Edited on 10.29.2009 9:46 PM PDT]
