Answering to my own post:

I found out that the error is related to x264 encoding option
"direct_8x8=-1". Without this option the script works.

Does anyone know what this option is good for? In the man pages I found
nothing about it.

Maybe so far you were deterred by the script mentioned in my first post
so I peeled out the command as such:

mencoder dvd://n -dvd-device /path/to/dvd -oac copy -channels 6 -vf
pullup,softskip,crop=688:336:16:114,harddup -ovc x264 -x264encopts
