Unable to mount cdrom?

[fvs]

Iv'e been trying to play my cdrom, Can't seem to get it working, I tried the following and can't seem to get it right, need help.

root@fvs:~# chmod 644 /dev/hdc
root@fvs:~# mount /dev/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: you must specify the filesystem type
root@fvs:~# pico /etc/fstab
root@fvs:~# chmod 644 /dev/cdrom
root@fvs:~# mount /dev/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: you must specify the filesystem type
root@fvs:~
What do I do for filesystem type?

[kern]

why are you changing permissions on the device?

[kern]

[shaunb@earth]/home/shaunb:# grep cdrom /etc/fstab
/dev/cdrom       /mnt/cdrom       auto        noauto,owner,user,ro  0   0
[shaunb@earth]/home/shaunb: #

This is the entry you should have for /dev/cdrom in your /etc/fstab, as long as its the same, you can just type

mount /mnt/cdrom

[kern]

WAIT a second

you're trying to PLAY your cdrom? does this mean its a music cd?

you don't mount music cd's, this is why its asking you for a filesystem type, because the disc isnt in ISO9660 format.

just put the cd in , and start a cd player application

OK, I tried another player "Amarok" and it played the music cd, Now I need to get my DVD player to play, I tried using xine to play and it wont play after it launches?

[kern]

You need to install the libdvd-nav and libdvdread packages

I did the install, but I get this error "could not access /dev/dvd" What next?
PS Thanks for staying with me.

[kern]

add yourself to the disk group and you should be able to read from /dev/dvd

its usermod <user> -G disk

or something like that

[fvs]

Please expain how do I do that?

[kern]

ok, I'm sure this method works too,

edit /etc/group as root and find the 'disk' group,

it should look as follows

disk::6:root,adm

make it like this, put your username in, save and exit

disk::6:root,adm,youruserhere

now as your user, type

groups

and it will show your users groups

hopefully your user will now be in the 'disk' group and able to read the device, you might need to logout and log back in, or if the editing /etc/group by hand doesnt work, we will have to use 'usermod -G' (if I can remember the command, havent done this for a while).
