I don't recognize these messages, but I think they indicate that you
specified 'dvd://mnt/cdrom' on the command line, and that that is (as my
own memory indicates) incorrect syntax. 'dvd://' or 'dvd://NUMBER' would
be correct. MPlayer appears to be falling back to simply 'dvd://'
because it doesn't recognize the track number.
For future reference, please always provide the exact command line used
as well as the full output when reporting a problem.

This isn't really an MPlayer question, it's a general
*nix-file-permissions question. Still, I'm feeling helpful this evening.
Who owns /dev/dvd, and what are its permissions? What groups are you a
member of?
My /dev/dvd is
lrwxrwxrwx 1 root root 4 2008-09-15 22:18 /dev/dvd -> scd0
That's a symlink to /dev/scd0, which in turn is
brw-rw---- 1 root cdrom 11, 0 2008-09-15 22:18 /dev/scd0
That's readable and writable by owner (root) and group (cdrom).
The 'groups' command tells me
wanderer dialout cdrom floppy audio video plugdev users
and that indicates that I am a member of the 'cdrom' group; therefore, I
can access the device.
