I own all of the DMC sound DVD books, but none of them have any ALDA nr, only ISBN ,barcode,and the numbers on the DVD itself(the ones in the inner circle) aren't the ALDA numbers at all=> I didn't find any ALDA numbers anywhere on the DVD,book,Obi,registration card,that's why I replaced them with the ISBN,sorry if this was a mistake
The releasedates I have directly copied from the last page(where all the crediots are) of the books.
