Does the debian package of libdvdread contains the CSS stuff ? Also, the
lack of "using_dma" is annoying... It looks like our CD/DVD kernel
driver is still dumb and still switches DMA off on any stupid error...
Have you tried booting OS X and playing the DVD once ? Maybe the drive
wants a zone to be set at least once, which MacOS does the first time
you play a DVD
