The DVD case has nothing to do with the picture, and most DVD9 895 pesos Magnavision titles (including Munich) are just as good as R1 releases with the features intact. Look at specific threads for discussion about those titles.
The budget 475 Magnavision however are DVD5 and lack some features of the R1, and picture quality sometimes suffer and noticeable if you have a big-screen theater setup.
I do agree that most Magna titles have poor cases but as long as they are imported DVD9, and are identical to R1 releases, I am satisfied...
