OK. Sorry about that, I should have checked the previous tickets more

Could you explain for me why dvd's must be mounted as udf and why it is
a problem if not?

As mentioned in another post my fstab line is setup with udf,iso9660 as
the default filesystem but all my discs get mounted as iso9660.  If I
set the fstype to auto the same thing happens.
The only way to get udf is to set fstype explicitly to udf.  But this is
not a solution, since my system is then unable to mount any cd's or data
(Note, I've tested this with a variety of dvd and cd formats).
