Also, avoid those slim-line cases if they were designed for CDs.  CD
cases have a tighter hub-grip than DVD cases because of the risk the two
polycarbonate layers of a DVD pull apart!

As usual, Mike is quite correct. I might add incorrect volume and file
structure logical errors as a third, common source of premature failure.
Such discs "work" in some operating systems, but fail is others or later
versions of a "good" O/S.
