dvd+rw-tools DVD player incompatibility
The problem is that DVDs created with these tools (and some others) are
not compatible with certain portable DVD players, for example some of those
installed in automobiles. However, the very same images created with either
Nero (Linux) or with the Windows equivalents are % compatible. Not sure if
this is a problem with growisofs or the underlying mkisofs/genisoimage.
Of course, I would consider this a failing of the players themselves or the
media if not for the fact the Nero (Linux) and Windows utilities produce
working DVDs using the same media.
