Well, I did another rigorous debugging: no more ripped VOBs - this time
I took my trusty Kurosawa's Ran disc and run encode directly on DVD data.
Segfault once again.
Running in gdb yields
(gdb) run dvd:// -nosound -ovc lavc -lavcopts vcodec=mpeg4 -o test.avi
Starting program: /usr/local/bin/mencoder dvd:// -nosound -ovc lavc -lavcopts vcodec=mpeg4 -o test.avi
