I have been sifting through all the threads posted and don't seem to find a solution to the problem I have. I have a Sony HDR-SR1 Handycam and cant seem to get my mac to register the AVCHD movie clips I have made. In a slight stroke of genius i reduced the camera definition from HD to SD. When recording in SD I am able to import the movies but there seems to be a problem with the HD. Anyone have some ideas for me?
