We still use iMovie HD aka iMovie 6.0 because I’m not ready to give up all the money we’ve sunk into plugins to “upgrade” to iMovie ’08.
But today I ran into a problem we’ve had before. I thought it was a cable problem (firewire cable), but in reality it is an iMovie problem. Sometimes iMovie stops recording audio. You will hear it record, it will be on the clip in the clip pane, but when you move it to the timeline to edit – no audio. The solution is to disconnect your camera cable from the mac and restart iMovie. Then reconnect everything – it works.
