Sound gets distorted before even being burned

ok im trying to burn wild hogs. ut was a bin cue file i burned it to image cd-r yadda yadda. i can go into the mpeg folder and it plays fine. but when i run nero make dvd movie and go through everything when i get to th test screen where you can test if the play button plays it ect. the sound is distorted. and when its burned its distorted. ive had this happen now on this and casino royale. its done it with a couple AVI movies also. what is causing this from the file being perfectly fine to when nero loads it in the sound goes bad? note i have burned a couple movies earlier in the week and it did just fine.
