Both files may be corrupted, redownload them.. If they are not corrupted then:
disable ffdshow / uninstall ffdshow
To disable ffdshow when playing this bad DivX movie (or XviD one):
in BSplayer rightclick, open options, open filters, find ffdshow on the list (if there is no item called "ffdshow blablabla" then you are not using it), click on it.
In codecs section, change "decoder" column to "disabled" for first 4 rows (xvid and 3 divxes).
click ok, and restart BSPlayer.
