Ok i had the old version of k-lite and so i upgraded to the new because I downloaded a MP4 and needed new codecs for it well i did it works GREAT....but, when i open up my old .avi movie files (aka DVDRIPS) say through media player 10, power dvd, real player I get the audio commentary playing throughout the movie. Im pretty sure its the new codecs my question is how and where can i turn this option off? P.S. ive tried power dvd audio tracks but its not highlighted (not clickable)
