I don't know much about the cd-rom stuff on osx but I expect there are
much more issues of which some are more severe than this (and the
solution might fix all the issues). I believe that on osx there is no
such thing as direct cd-rom access (anymore) and due to this I think
wine can't read audio tracks, neither can we write CDs from Wine or
read special data tracks needed for e.g. copy protections. As far as I
remember Transgaming wrote their own cd-rom driver for this, so
perhaps that's the direction we should head into as well else we will
never get copy protections working on OSX.
