I am using dvdbackup under testing, it is giving some errors I did not expect and don't know whats the fix.
fred@debian:~$ dvdbackup -i /media/cdrom0 -I
Floating point exception
fred@debian:~$ dvdbackup -M -i /media/cdrom0 -o /home/fred/dvdback/
Can't read title from DVD device /media/cdrom0
You must provide a title name when you read your DVD-Video structure direct from the HD
fred@debian:~$ ls /media/cdrom0
