i'm trying to finish this project, but i'm realizing that when I try to set the volume of a clip to 0%, it doesn't mute it entirely like it used to. and the audio on a clip fades out at the beginning and end even though i have the fade in/fade out manually set to 0 seconds. what's up? please help! this has to be in by tonight!!!

ps: i've tried restarting the program, and the computer. i have imovie 08', and haven't done any mac software upgrades, like upgrading to snowleopard or anything.
