skips

In civilization 4 wheni start the game the fraxis movie sound skips. As if its a broken record. This happens with all the CG movies in the game. For e.g: When we build a wonder then the movie plays but the sound skips. I know its some thing got to do with config file but i don't know what to...

i need to remove the words like F*** and S*** in an mp3 file, how do i do it the professional way? all these days i used to cut that portion and it would sound really bad. but the skips in radio are good, only the vocals are removed...not the music. if not that good, atleast suggest something...
