i assume your talking about backing up your xbox games onto a dvd-r disk? ... well if you are u gotta use a program like QUIX to make your xbox games into ISO files (must use a program like quix since it stores it in the xbox ISO file format) then once u make the ISO files, just use nero to burn it to a dvd disk... and thats pretty much that.
if your trying to backup your original xbox games from there original disk's... just load up a program on the xbox called "dvd2xbox" rip the games into the hard drive... then login to the xbox with QUIX then make the ISO.
have fun
