automatic mount udf on the DVD - rights

I have CENTOS 6.3 and I use the DVD with created filesystem UDF.
When I put my DVD to PC all is working fine and UDF is automaticaly mounted and I have folder LinuxUDF.

But I would like to change rights on that folder during atomatic mounting. I can not find where is it possible to set it.
I tried udev, autofs ... but without success.

Have you got any idea where to find it ?

I am not completely sure, but do you have an entry for mounting DVDs in your /etc/fstab?
I so than you could change rights there.
But what do you need to change? A DVD UDF filesystem will be readonly anyway.

also keep in mind that 6.3 is UNSUPPORTED
there have been NO updates to it for almost TWO YEARS
it is 3 versions out of date

please upgrade to the ONLY supported version of 6
CentOS 6.6

There is no record about DVD in fstab because the mounting process is automatic.
When the record was in fstab the DVD with UDF fs was mounted to /media/LinuxUDF(1) because I had to create folder /media/LinuxUDF as mounting point before that.

I would like to find where is information that UDF fs is mounted to /media/LinuxUDF with rights full acces for owner and no access for group and the rest of world.
There is somewhere defined umask=0077. For example when I put CD to PC it is mounted automaticaly but with umask=0022.

I can see this issue in mtab or when I use command mount. Here I can see value of umask.

So I have to find where is this definition. I thought that it could be in udev rules but I did not find it.

Even Centos 6.6 have to have this definition somewhere.

My problem is that when user A put DVD to PC in Gnome then this DVD is not accessible to user B when users A and B are switched.
I think that one of posible solution is create groupe GG and put user B to this group. Then user B will have accessible folder where is mounted DVD with udf. So I would like to find where is issue for change umask for udf filesystem.
