I haven't had major nugs with bsplayer and I have been using it for about a year and a half now.
I guess bugs come from the fact your register is a "mess" . if you clear your HD every 6 months or so, you don't have those bugs.
the all problem is your system instability! ( instabilit?© in frencf
)
a lot of people have those problems by not cleaning the register or not uninstalling softs properly!
all this to say that more your OS is buggy more bsplayer gets buggy
