There are green letters when i play a video on my wmp 11 for vista, how do i turn it off?

i want to watch my movies with out those letters. it indicates the rate of the audio track of the movie. i imported it to my acid pro 6 to make a ringtone from a clip i like. and made it. i didnt save any thing. and now most movies, usually avi, display the audio info. i also have two encoders, ffdshow, one for audio and one for video.
