so this should work fine on my d3....which its not...every time i downgrade back to the 07 discs...reburn a dl dvd correctly...it updates and resets and then it keeps asking for the appropriate disc....so i have to downgrade again start the whole process over again...ive tried 6-7 times now with no luck using different name brand media, different burning programs, and even different DL burners....wtf
