[dvd::rip] cannot open device with libdvdcss

Could someone please point me in the right direction for fixing the
following problem? 

/dev/dvd is symlinked /dev/scd0 which is a SONY CD-RW CRX216E rev.PDO1
IDE-ATAPI with scsi emulation.

---------------------------------------------------------
Job 'Determine number of titles' failed.

Executed command: dr_exec tcprobe -H 10 -i /dev/dvd && DVDRIP_SUCCESS

Last output was:

libdvdread: Using libdvdcss version 1.2.8 for DVD access
libdvdread: Could not open /dev/dvd with libdvdcss.
libdvdread: Can't open /dev/dvd for reading
(iodump.c) unable to open directory "/dev/dvd"
