content: Like a previous reviewer, the set I purchased is defective. The disc labeled 4 and 5 plays 1 and 2. Despite lengthy correspondence dating from April 06 with Deutsche Grammophone, they have not sent me a replacement. Needless to say, I have not bought a DG product since and may never again. A shame, since I had my eye on the Karajan Beethoven DVD set. I had the impression that DG had a high reputation for quality despite high prices. I am dissapointed to learn that only the latter is true.
