I'm making a video and whatever I do the audio fails and doesn't play anything when I preview movie! It plays a half second of the audio then nothing! only small static every once in a while. I have tried to alter the preferences to change it to aif. mp3. wav. n' stuff but it all fails! I only want to put in a three min. clip from a audio podcast. I have also tried putting it through "Soundtrack" into Garage Band, or just straight into garage band! HELP! ANY Ideas will help ALLOT! Thanks!
