Cannot read dvd's from drive


I recently installed mplayer and acidrip (thanks acid_kewpie), and everything else (such as lsdvd, gtk2, libdvdcss, libdvdread, glib, extutils-pkgconfig, extutils-depends, etc.) I also setup my user to have permissions for the cdrom drive.

Everything installed fine. I can play files off of my hard drive with mplayer, even with the gui. acidrip opens fine. But they both report that they cannot read from dvd's. Regular cd's work just fine, and I can mount and read the files from dvd's.

When I run lsdvd from the term, it reports:

Code:
libdvdread: using libdvdcss version 1.2.9 for DVD access
libdvdread: Could not open device with libdvdcss.
libdvdread: Can't open /dev/dvd for reading
Can't open disk /dev/dvd!
Any help would be appreciated. Thanks

You may have already checked this, but is there a /dev/dvd symlink pointing to your actual DVD device (such as /dev/hdb, /dev/hdc, /dev/hdd, etc.)?

If not, do this:

Code:
ln -s /dev/hd<whatever> /dev/dvd
Hope that helps.

both /dev/dvd and /dev/cdrom are pointing to /dev/hdc

I seem to recall this problem when I was running Slackware 10 a while back. What are the permissions on /dev/hdc?

Code:
ls -l /dev/hdc
Make sure that your user has read permission for that device. If only the group, such as cdrom, and the owner (root) have read permissions, then you need to be a member of that group. To see what groups you are in, you can do the following:

Code:
groups
If you are not in the necessary group, try this:

Code:
gpasswd -a <username> <groupname>
Let me know how that works for you.

ls -l /dev/hdc:
brw-rw---- 1 root disk 22,0 2002-06-09 1427 /dev/hdc

cat /etc/group | grep cdrom:
cdrom::19:blueAlien

groups:
users cdrom burning floppy audio video

** Tried adding myself to the disk group, and also changing the group for /dev/dvd /dev/cdrom and /dev/hdc, but none of that worked... same problem

Hmmm...

It's less secure, but you can try changing the permissions on the device so that everybody can read from it. Try this:

Code:
chmod o+r /dev/hdc
If that doesn't work, you'll probably want to change it back like this:

Code:
chmod o-r /dev/hdc
