Now I'm trying to mount an UDF formated DVD that is mounted properly. It is and purchased DVD Video disk. This time everything works as expected. The disk is mounted and I'm presented with an window asking me what action I want take next. The default is to open Movie Player.
Some forums state that there are different UDF format versions. I've read complaints that say that UDF formated DVDs created with Vista are not accessible under Linux/Ubuntu (as Vista uses some specific UDF format). I don't remember where, but one guy was claiming that newer UDF formats store some permission settings and that's why some tweaks have to be made in /etc/fstab have to be made in order to make this kind of UDF DVDs accesible to normal users (instead of only to the root user???) I find this an important hint for where to look for when trying to fix this bug, moreover because I tried accessing the previous mentioned DVDs with the last line in /etc/fstab removed (as it was on a cleanly installed Maverick). I'm getting the same end results, and the only deference is that when the line is removed, the system mounts the DVDs in some other directory.
This is what i get when I remove the line and insert another UDF DVDs that is inacessible.

This time at least the medium is unmountable!
What I'm wondering is, if the fix for this problem should be in tweaking the DVD drive entry in /etc/fstab or somewhere else.
