For my understanding, you can use XBOXISO software convert games file to iso file then use Neor to burn it. Or, you can connect your XBOX to PC, then use FTP software upload all files to PC HD, After transfer all game files, use Nero burn to disc. I am not sure you have to fix media check file in default.xbe file. These are general ideals. There are many things to be take care. Due to 版主規定, I can not tell you all details.
