I have this too! I noticed that playing the stream with mplayer had no
problems. Doing something like:
mencoder <nuv> -oac copy -ovc copy -o <nuv.out>
rebuild the B-frames in avidemux now and all is fine....
I think that mencoder complains about duplicate frames or soemthing like
that (I don't have a log at the moment).
