After instaling the mplayer and libdvd packages from linuxpackages.net, I am finding that mplayer is refusing to use my DVD drive. If I run it from a shell, and attempt to access a film, it provides these error messages:

Playing dvd://1.
libdvdread: Using libdvdcss version 1.2.8 for DVD access
libdvdread: Could not open /dev/hdc with libdvdcss.
libdvdread: Can't open /dev/hdc for reading
Couldn't open DVD device: /dev/hdc

I have been searching around and have not managed to find a solution to this problem. This is my dvd drive's fstab entry:

/dev/dvd /mnt/cdrom iso9660 udf,noauto,users,owner,ro 0 0

Mplayer can access the drive if I mount it, but libdvdcss cannot, so it will not play encrypted DVDs. Besides, I read somewhere that the drive does not to need to be mounted to enable cd play back. What could I possibly be doing wrong here?

Thanks in advance.

Change :
/dev/dvd /mnt/cdrom iso9660 udf,noauto,users,owner,ro 0 0

to:
/dev/hdc /mnt/cdrom iso9660 udf,iso9660,noauto,users,ro 0 0
(remove owner: owner of /dev/hdc=root and add iso9660 fs in case of)
