Andrew,
Thanks very much for replying to my email. I appreciate it.
I think what really matters is the permissions on /dev/cdrom or
/dev/hdc depending on how you're set up. check those. they should be
root:cdrom. Also, what mechanism are you using for mounting these
disks? You may have to monkey with its config to get the permissions
of the mounted disk the way you want.
Hmmm.
[EMAIL PROTECTED]:/dev$ ls -l hdb
brw-rw---- 1 root disk 3, 64 2005-02-26 06:38 hdb
[EMAIL PROTECTED]:/dev$
I assume this should be cdrom not disk correct?
Trying to remember how I set up the dvd drive to mount automatically
when a DVD disc is inserted - I seem to recall using a program called
"automount" and the following line are in /etc/auto.misc:
cd -fstype=iso9660,ro,nosuid,nodev :/dev/hdb
Following line found in /etc/auto.master:
/misc /etc/auto.misc --timeout=60
And that seems to be all that I could find.
Reading the man pages of automount doesn't show anything about groups.
I tried disabling automount, and mounting the CD myself as a normal
user, it could mount, and I could see what was in it, but I couldn't
play back the video as piers, but I could play it back as root. I
SSH'ed into Hinata and tried the following command as user piers:

As I was SSH'ing in, the X11 display errors are obvious, but it shows
that the DVD would have been played back fine.
Interestingly, if I mounted it as user piers, the users and groups are
garbled:
