Help - video stops playing after few seconds and won't work after that
 

Hello
I've had this random lag on BS player for a long time. So, the problem is when I'm trying to open any file via BS player video just stops in like 5 seconds and stops working entirely. I have tried to re-install BS many times without any success. I have the latest version (2.69) of free BS and I downloaded it from the original site. And I also think that the codecs are fine since the installer recommends them to me automatically. Any advices to solve the problem?
