Ok, i'm worried now, i've looked constantly and i just need a quick and easy answer thanks. Do backups only run on hitachi v78 if they are burned with Pioneer 111d?

NO. . .the 111D is simply the optimal drive to burn your 360 games on due to the fact that it automatically set it to the correct BOOKTYPE. . .it is good for burning any game for any model of the box. . .

no, they should work on any modded box. the pioneer is just a drive that is known to be compatible with making backups .

I think particularly because it has automatic bitsetting. you don't have to get that one though, there's others that will work as well.
