I have imported an iMovie project into FCE HD according to the method described in the manual (using Open File). I followed the instruction to Render All but when I play back my sequence in the Timeline I do not hear the audio component attached to each videoclip. Instead, I get an annoying repetitive beep (something to do with timecode?). ...When playing back the clips in the viewer however the audio is there and sounds fine. Has there been a rendering problem or am I missing something?
