Don't want to derail the thread, but UDF is a "real standard" and not an "Apple standard".
UDF is an improvement over ISO9660 in many ways.
Most, if not all, DVD discs are actually UDF formatted with a ISO9660 compatibility layer.
UDF is the new ISO9660.
(I'm not saying ocicat doesn't have a point in general, but this is the wrong example
)
