It's not mencoder per se, but either vd_ffmpeg.c or libavcodec. For
some reason it thinks something has changed in the stream which
requires reinit, but reinit is broken in mencoder.

BTW, I've never seen this happen, and I assume it does not happen
unless you cat vob files together, which is the wrong way to encode a
DVD. You should always use dvd:// (with -dvd-device pointed to the
fake DVD root if you copied the vobs off the DVD) or dump the whole
title with mplayer -dumpstream.

All the cat *.vob | mencoder stuff should be removed from the DOCS...
