Wow...I have to whole-heartedly disagree.  I'd argue that what you
describe has nothing what so ever to do with standards. The fact is
that most (but not all) dvd players will ignore corrupted sectors and
the like which is obviously *not* the case (by design) when a computer
tries to read a drive of any sort.  This is just the dumb luck that
the DVD player manufacturers decided to just deal with such situations
as best they can.  I can assure you there's nothing in the DVD
standard that says you can corrupt sectors at will, and that the
player needs to allow for that.  As a matter of fact there have been
Sony DVD players that barf on their own copy protection.

Quite the contrary, many argue that things like Sony ARccOS actually
violate the DVD standard and warrant a class action suit...and I
totally agree.
