"--nosync " did not improve, but looking deeper into the resulting ogg
file i noticed that the framerate was set to 60fps, while the original 
had 25fps.

forcing "--inputfps 25" then did indeed do the trick for that video and
the result was satisfying.

i wonder however why ffmpeg2theora had a problem to determin the
original framerate, "ffmpeg -i" showed it correctly.

is it worth filing this as a bug?
