MeBe has captured his footage at quite a low contrast... so blacks are not black but dark-grey, whereas whites aren't completely white either. Now, using my old ghost removal method (basically using the Exorcist filter, or AviSynth's pendant Ghostbuster) works without any of the problematic artifacts, because they resulted from blacks already being perfect black and whites being perfect white in the captures (as it was the case with the clip I got from you).
