Just to be sure, you need to change the mp3 outside of FCP. You can use QT Pro, MPEG Streamclip and other programs to do that. FCP rendering it internally won’t do it right. The only other thing I can think of is if the gain exceeds 0 and the audio clips, that could cause a dropout effect.
Have you trashed prefs and repaired permissions? If not, do that, too. There’s a tutorial about how to do that on the Cow.
