This looks like mplayer is accessing the drive, but
cannot play the file. A "missing codec" error should
look different.

So you can exclude media error.

Maybe this "diagnostic script" from my outbox can
help you to track down the error. It has been "made"
on 7-STABLE i386 with mplayer-0.99.11_3 - a quite
old system. See if the steps described here can be
reproduced on your system in a similar way.

Here's an example of my "THX 1138" movie DVD:

Step 1: Identify media

	% cdcontrol info
	Starting track = 1, ending track = 1, TOC size = 18 bytes
	track     start  duration   block  length   type
	-------------------------------------------------
	    1   0:02.00  206:28.68       0  929168   data
	  170  206:30.68         -  929168       -      -

Step 2: Identify file system

	% file - < /dev/acd0
	/dev/stdin: UDF filesystem data (version 1.5) 'THX_1138        '

Step 3: Mount file system and check content

	% sudo mount -t cd9660 -o ro /dev/acd0 /mnt

	% ls -R /mnt
	audio_ts/ video_ts/
	/mnt/audio_ts:
	/mnt/video_ts:
	video_ts.bup* vts_01_1.vob* vts_02_0.bup* vts_03_0.vob* vts_05_0.bup*
	video_ts.ifo* vts_01_2.vob* vts_02_0.ifo* vts_03_1.vob* vts_05_0.ifo*
	video_ts.vob* vts_01_3.vob* vts_02_0.vob* vts_04_0.bup* vts_05_0.vob*
	vts_01_0.bup* vts_01_4.vob* vts_02_1.vob* vts_04_0.ifo* vts_05_1.vob*
	vts_01_0.ifo* vts_01_5.vob* vts_03_0.bup* vts_04_0.vob*
	vts_01_0.vob* vts_01_6.vob* vts_03_0.ifo* vts_04_1.vob*

	% sudo umount /mnt

Step 4: Play DVD content - ATTENTION - DVD not mounted for that!

You don't have to use -alang or -aid as mplayer will default to the
(for you correct) english language defaults. In this example, track 2
is the 1st part of the actual movie.

***

Also try what happens if you mount the DVD and use mplayer
on a VOB file directly, e. g. "mplayer /mnt/video_ts/vts_01_1.vob".
The output should be similar...
