It giving me “Invalid and inefficient vfw-avi pack B frames detected”. Will I can play avi file just fine. I’m not having a problem playing anything. But as I start my mplayer wih avi file( I have not test any other file other then avi). It always give me this Error and can’t seem to figure out why. I think my setting are just find. I just don’t want this error keep poping up when I start my mplayer.
