Seems like I ran into a similar problem as
https://trac.mplayerhq.hu/ticket/2172


using MPlayer SVN-r36775-4.8.2 and MEncoder SVN-r36775-4.8.2

no matter if I call:

mencoder -ovc raw -noskip -forcedsubsonly -nosub -nosound -mc 0
- -lavdopts threads=8 -of rawvideo -o NUL -dvd-device
"F:\TestClips&Co\DVDs\ElephantsDream" dvd://1

or

mplayer -lavdopts threads=1  -aspect 1.77778:1 -mc 0 -nosound
- -nomouseinput -nokeepaspect -monitorpixelaspect 1 dvd://1 -dvd-device
"F:\TestClips&Co\DVDs\ElephantsDream\VIDEO_TS" -forcedsubsonly -nosub
- -noautosub -fps 25 -vo direct3d

I get:
MPEG: Missing video stream!? Contact the author, it may be a bug

mplayer&mencoder were build using:
https://github.com/jb-alvarado/media-autobuild_suite


!This happens for me with every DVD not just elephants dream!

think I found the problem if I use:
mplayer dvd://1 -dvd-device "f:\TestClips&Co\DVDs\ElephantsDream" -vo
direct3d
the input is handled fine
if I add '-nosound'
mplayer -nosound dvd://1 -dvd-device
"f:\TestClips&Co\DVDs\ElephantsDream" -vo direct3d
I get:
MPEG: Missing video stream!? Contact the author, it may be a bug


>> Same happens for mencoder, as soon as '-nosound' is present DVD
handling fails. <<

Cu Selur

Ps.: I also just tested with latest svn version "MPlayer
SVN-r36824-4.8.2" where the problem is still present
