I hate to chime in with the "me too" emails, but me too.
I was in the middle of ripping and converting a bunch of DVDs when
I happen to do an ffmpeg upgrade.  Now vob -> avi doesn't work, same
error.

FWIW, I'm using this command
ffmpeg -i SIMPSONS_S10_D21-1.vob  -f avi -vcodec mpeg4 -b 800k -g 300  
-bf 2 -acodec mp3 -ab 128k simpsons.avi

I have the same results from the ffmpeg -formats as you as well.
