I am experiencing problems when trying to read DVD-Rs or DVD+Rs recorded by different TV DVD Recorders. Usually the problem is that when I try to manually Mount the dvd with the udf option (with auto option same output):
giankun@giankun-imedia-S3810:~$ sudo mount -o ro -t udf /dev/sr0 /media/giankun/dvd
mount: tipo fs errato, opzione non valida, superblocco su /dev/sr0 danneggiato,
codepage o programma ausiliario mancante, o altro errore
In alcuni casi si possono trovare informazioni utili in syslog. Provare
ad esempio 'dmesg | tail'
Which says "fs type wrong, invalid option, superblock on /dev/sr0 damaged, etc. And dmesg | tail

And this when I try to mount as iso9660
giankun@giankun-imedia-S3810:~$ sudo mount -o ro -t iso9660 /dev/sr0 /media/giankun/dvd
mount: tipo fs errato, opzione non valida, superblocco su /dev/sr0 danneggiato,
codepage o programma ausiliario mancante, o altro errore
In alcuni casi si possono trovare informazioni utili in syslog. Provare
ad esempio 'dmesg | tail'
with relative dmesg | tail

I think this is not a problem with my hardware because on the same machine W7 (I have dual boot) can read the disks and extract the files (most of those disks must then be decrypted since they are CPRM encoded coming from a Japanese DVD recorder). However the drive is an ATAPI DVD A DH16ABSH. I already tried switching to IDE mode from AHCI (bios setting) but nothing worked.
I must add any other disk (including DATA DVD and original Video DVDs) is correctly mounted. Is there a way to Mount these particular disks? Is this a known bug (I have found some short references of people having the same problem online, but no solutions like in this discussion)?
Here is what I can exctract from one of those disks by Nero, KB, and a Windows util I downloaded:
