dvd's don't play: not sure why? [SOLVED]

Hi all,

I'm trying to play dvd's in applications (totem, mplayer,vlc) but Arch won't play nicely   Here's my fstab:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0
tmpfs                  /tmp          tmpfs     defaults            0      0
usbfs                  /proc/bus/usb usbfs  defaults            0      0

#/dev/cdroms/cdrom0     /mnt/cd   iso9660   ro,user,noauto,unhide   0      0
#/dev/cdroms/cdrom0     /mnt/dvd  udf       ro,user,noauto,unhide   0      0
#/dev/floppy/0          /mnt/fl   vfat      user,noauto             0      0

/dev/sdb3 swap swap defaults 0 0
/dev/sdb4 / reiserfs defaults 0 0
/dev/sdb2 /boot reiserfs defaults 0 0
/dev/sdb1 /mnt/files ntfs noauto,user,rw,gid=100,umask=0000 0 0
/dev/cdroms/cdrom1 /mnt/dvd auto user,noauto,unhide 0 0
/dev/hdc                /media/dvdwriter        auto    user,exec,noauto,comment=managed 0 0
/dev/hdb                /media/cdwriter         auto    user,exec,noauto,comment=managed 0 0
/dev/fd0                /media/floppy           auto    user,exec,noauto,comment=managed 0 0

I added the line

/dev/cdroms/cdrom1 /mnt/dvd auto user,noauto,unhide 0 0

just now to test if it would work that way... and it did! So why doesn't it normally?
Needless to say, a trained eye can see that normally I don't mount my dvd and cd drive manually: they are done by HAL or UDEV if I'm right?

If I try to use totem without my added line above, totem shows an error "/dev/hdc: permission needed" I'm guessing this has something to do with my problem...

P.S. I am in the following groups: users, audio, video

Thanks

What is the output of ls -l /dev/hdc ?
It should be root:optical - if you have this add your user to group optical and try again.

Latest udev has also some changes that can do wrong group permission. If you have root:disk read this:

lanrat, you were right! so this is the case then? optical is used for (duh!) optical drives and their playback?

Re: dvd's don't play: not sure why? [SOLVED]

It's just used for /dev/hdc - you can't have many group permissions for one device :-)

I don't know how it works internally in a dvd player but it complained about an access to /dev/hdc.

Re: dvd's don't play: not sure why? [SOLVED]

I had the same problem and I am in the optical group. Some programs will not look at /media/dvdwriter or cdwriter for access. What I had to do to get it to work was to symlink the /media/dvdwriter to /mnt/dvd and cdwriter to /mnt/cd. This made my other apps recognise the cd's/dvd's.

But, how can I force in fstab to add ro to the options line. If I manually put it in, then, on a reboot, the ro option is gone.

Thanks!!!

If you are reffering to the options of the /media/... drives, then I have the exact same question... after reading the docs I cant see a solution (you need to read up on fstab-sync) If I get a solution I'll post it here
