do you have to have a dvd burner or can you use a regular cd or cdrw burner?

well if the backup will fit on a cdrw you can burn it on that...if not then yes you need a dvd burner

i would say more games need a dvd burner than not?

dvd burner is the way to go since it will also
burn cdrw's if it's a pioneer dvd burner

maybe your box won't read cdrws or cdrs....
