movie is tearing apart

[mavrick]

i've been using this prog since it's first release.
using the last releases i've encountered the strangest problem:
the movie seems to be tearing apart. like the program can't handle the advanced bitrate.
first. i thought it's a problem with the divx decoder configuration. selecting the options in the quality settings (smooth playback` couble buffering...) didnt help much.
i am not experiencing the same problem on windows media player or any other prog, yet i prefer bsplayer for it's convenience of use.
would love to get some help concerning the mentioned problem.
thank you in advance.

p.s.
i noticed that others complained on the same problem in this forum (october) however, no solution was obtained.
