Problem reading multisession DVD

I have a problem reading a multisession DVD, I was able to read the dvd when it has only one session but after burning a second session It opens like if it was blank I have tried the following:

linux-axcd:/home/eduardo # mkdir DVDlinux-axcd:/home/eduardo # mount -t iso9660 -r /dev/sr0 /home/eduardo/DVD
linux-axcd:/home/eduardo # cd DVD
linux-axcd:/home/eduardo/DVD # ls -l
ls: leyendo el directorio .: Error de entrada/salida
total 0
linux-axcd:/home/eduardo/DVD # 



and if I open the DVD folder in dolphin it opens an empty forlder, the dvd is readed fine in windows pc, the first and second session were burned with burnaware professional in windows 7

Note: This is not the first time that this happens, with this and previous versions of opensuse

thanks

This command did the trick

linux-axcd:/home/eduardo # mount -t udf /dev/sr0 /home/eduardo/DVD
mount: /dev/sr0 is write-protected, mounting read-only
linux-axcd:/home/eduardo # cd DVD
linux-axcd:/home/eduardo/DVD # ls -l

this is where I found the answer

http://askubuntu.com/questions/359264/how-to-open-udf-volume

But why openSUSE doesn’t mount this DVD automatically?
is for the UDF file system?
How can I setup openSUSE to mount this type of DVD automatically?
