Problem with BSPlayer 086.494

[Bede]

Got the same problem after having run several avi-s OK. And can't figure out why :( .
Even worse still: once I had to unplug my PC cause my XP got lost somewhere in deep space while running BSplayer.

I saw 2-3 movies OK.
Then, the first weird thing weid thing was I got some green stripes running from top to bottom while Bsplayer was running, which scared me that I might have a problem with my videocard. After rebooting I got to see the very same movie using AceDivXPlayer without any problems.
Afterwards I got to have the much worse problems I described above.

Still, what I appreciated at BSPlayer was that - at least for some movies - I could see the subtitles (.sub files) (not that, for the movies I watch, I would personally need those, but there are some who really need them).

Would that have anything to do with some software I have?
One thing I did install was AC3 filter. Then, after watching a couple of movies began all the problems.
Or what???
