of course it will appear as a disc in finder - it records to DVD correct?
You should be able to open the disc and do what the second post said.
I believe it records to MPEG2 correct?
Have you tried the log and transfer in FCE? Plug your camera in, open final cut then hit command+shift+8 and it will come up. wait a few minutes to see if the clips will load in the new window. If not add them manually - theres a folder button that will let you browse, just choose the mounted disc on your mac.
