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:

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

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?

What is the output of the following command?

Code:

mount | grep cdrom0

htamayo · 11-27-2008, 09:44 AM

the output was:

Quote:

tamayo@350z:~$ sudo mount | grep cdrom0
/dev/scd0 on /media/cdrom0 type udf (ro,noexec,nosuid,nodev,user=tamayo)
tamayo@350z:~$

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.
