Public bug reported:

Can't access auto mounted UDF DVD. DVD is auto mounted to /media/SONATA_VOLUME 
on insert.
See permissions of /media/SONATA_VOLUME bellow! Drive icon also disapeared from 
nautilus.

There is no problems, when ripping with AcidRip specifying /dev/dvd as
source path. Also running: mplayer dvd://0 works without problems.

Running: Ubuntu lucid (development branch) 
Release: 10.04
