My VLC was working fine then all of a sudden the audio and the video are out of sync --- the audio is ahead of the video. I've check tried diff. vids and they do this now, the vids are in .AVI format. I also just installed a 'codec'(??) that would allow me to play XVID through QT that's called Flip4Mac. Is this what could have screwed up my regular .AVI playback? What should I do to restore my ability to properly play .AVI's with VLC?
