Burnt a dvd-r, don't know what kind they are, they're my brothers', and they're just black cases w/ silver tops and purple bottoms. Anyway, I downloaded an iso from Transmit (FTP for mac) and I burnt the dvd using Toast, a Roxio software for mac. I got the iso and burnt it as an image like i read on the forum. From the main menu of the xbox, i put the dvd in and the black screen w/ the xbox logo comes on like it's going to work and it goes back to the main menu and says that it can't read the dvd-r. Does anybody know what i'm doing wrong and how to make this work? Maybe it's the file from pc to mac that messes it up? If anyone could help that would be cool. Thanks.
