[gentoo-user] /dev/dvd playing up

[Antoine]

Hi all,
I got a new kernel and now can't get dvds to play. Does anyone have any
suggestions? I searched for ages but never got a solution that works...

Using mplayer
antt@tux ~ $ mplayer dvd://1
....
Playing dvd://1.
libdvdread: Could not open device with libdvdcss.
libdvdread: Can't open /dev/dvd for reading
Couldn't open DVD device: /dev/dvd

/dev/dvd is there - but I am not sure if this is right.

antt@tux ~ $ ls -l /dev/dvd
lrwxrwxrwx  1 root root 3 Aug  7 13:34 /dev/dvd -> hdc

Changing it to /dev/hdc does nothing...

trying mplayer dvd://1 -dvd-device /dev/hdc doesn't work either, though
I can mount the dvd manually and access it that way, though of course I
can't play it normally.
Any help appreciated.
Cheers
Antoine

How about "ls -l /dev/hdc" ?

My guess is that you have a permissions problem with your DVD device 
(/dev/hdc). Check the permissions there. Mine looks like this: brw-rw---- 1 
root disk 22, 0 Mar 10 12:47 hdc

If that is your case just `gpasswd -a <yourusername> disk` and you should be 
good to go. Don't bother trying to change the permissions on hdc since they 
will be reverted back when you next reboot.

Bingo... did that change somewhere? Since the gentoo 2.6.8r8 kernel? I
was not in the cdrom group before and the mount options has users...
I guess I should have thought of it, once again thanks heaps
