i´ve noticed that when i play video files in BS PLAYER, they are, not like before, running slower (interminttently)… i´ts like they lag( showing less frames per minute, so it does not freezes completely) and then continues playing normally…
Hard to say, Have you tried disabling avast to see if it improves? it could also be a problem with BS Player or it could be related to other software installed causing conflicts or maybe limitations in the amount of ram installed, other security programs running with avast :-\
