Description

On darwin and other bsd based systems, dvd_reader.c converts regular device
names to raw device names. e.g. "/dev/disk4" -> "/dev/rdisk4"
The test that determines if the conversion needs to be done is broken.
It was previously correct in libdvdread version 0.9.7. Looks like someone
"fixed" a "bug" without testing.
The following patch fixes it.
