problem accesing to a DVD movie don't have enough permission


Hi, this issue is weird for me:

I want to watch a DVD movie, after I insert the disc on the DVD drive I obtained this message:

Quote:
You don't have enough permission to see the content of "cdrom0"
I did a ls -la to the /media and the result was:

Quote:
drwxr-xr-x 11 root root 4096 2008-11-27 07:54 .
drwxr-xr-x 26 root root 4096 2008-11-27 07:54 ..
drwxr-xr-x 2 root root 4096 2007-11-15 15:50 binmounted
drwxr-xr-x 3 root root 4096 2008-10-28 15:44 boot
lrwxrwxrwx 1 root root 6 2007-05-08 05:26 cdrom -> cdrom0
d--x--x--- 3 4294967295 4294967295 88 2004-01-01 06:00 cdrom0
lrwxrwxrwx 1 root root 7 2007-05-08 05:26 floppy -> floppy0
drwxr-xr-x 2 root root 4096 2007-05-08 05:26 floppy0
-rw-r--r-- 1 root root 0 2008-11-27 07:54 .hal-mtab
drwxr-xr-x 2 root root 4096 2007-10-05 11:39 isomounted
drwxr-xr-x 2 root root 4096 2007-09-25 08:14 kingston
drwxr-xr-x 2 root root 4096 2008-11-07 16:13 usbdisk-1
drwxr-xr-x 7 tamayo tamayo 4096 2008-09-22 14:04 virtso
dr-xr-xr-x 1 tamayo root 12288 2008-11-06 03:13 xp
So the weirdest thing for me is:
Quote:
d--x--x--- 3 4294967295 4294967295 88 2004-01-01 06:00 cdrom0
First time I saw something like this.

My questions are:
1. who is that user (4294967295)?
2. how should I fix this problem?

Regards

What is the output of the following command?
Code:
mount | grep cdrom0

/dev/scd0 on /media/cdrom0 type udf (ro,noexec,nosuid,nodev,user=tamayo)

Ok. In the meanwhile I found an extensive discussion on a bug report, here. It looks like a problem with permissions setting for UDF filesystem (as for many DVD Video and as reported from your mount command). Despite there is still not a solution, some workaround has been suggested.

You can try to modify the relevant line in your /etc/fstab, for example if you have:
Code:
/dev/scd0       /media/cdrom1   udf,iso9660      user,noauto,exec,utf8    0  0
in /etc/fstab, try to change the order of the filesystem types:
Code:
/dev/scd0       /media/cdrom1   iso9660,udf      user,noauto,exec,utf8    0  0
Another user suggested to play the dvd from the command line, using
Code:
totem dvd://
Regarding the strange user and group ID, it is normal since the DVD structure uses a dummy ID of -1 and 4294967295 is -1 if interpreted as signed 32-bit integer. Hope this helps.
