So you ask me here to reproduce the problem I had and why I mailed the
mailing list :)
I did a copy of the VOB and then ran mencode -dvdkey $THE_KEY
~/mycopied.vob
with $THE_KEY=`mplayer 2>&1 | grep key` or something like this ( Indeed
I didn't do that, I did copy the key manually after an mplayer -dvd 2) .
And it didn't work because of failed authentication to the .vob
So i decided to mail here :)

Ok , got it , I have a pretty good knowloedge in shell so I knew that
"\n" is a \n and not a CR in shell, but I didn't knew how C parses shell
arguments .
