I have a Canon HG10 video camera and Final Cut Express 4 on my MacBook Pro. The FCE4 manual cheerfully says that the new Log and Transfer window automatically recognises AVCHD files when you connect your camcorder to your Mac. This didn't happen with me - the Log and Transfer window stayed greyed-out. I also tried importing the AVCHD files into iMovie but it doesn't recognise them either.
Any clues would be appreciated.
