Hey I really need someone's help please. I am currently trying to make a video for a school project, however I am encountering the problem of being unable to import videos into iMovie. I have never had this happen to me. I click 'Import Movie', I then select the mpeg video file to import into iMovie. However the progress bars showing the video being processed just flash by without actually filling and then the video isn't in the event in iMovie. But it is in the event when i look at it in finder.

Can anyone help me?
