Lethal: Do you happen to have a link to that utility so we could see if it'd solve the OP's problem, or is it a "distributed only with Sony cameras" kind of thing?
I was finally able to dig it up. Sony Plugin for M2T. Once it is installed use the Log & Transfer function in FCP.
Now, I don't know if this will work w/M2T files not generated by Sony's HDD or CF recorder. Also, there is a specific folder structure the M2T files need to be in for the utility to see them. The M2T files need to be inside a folder called "HVR" and that folder needs to be inside a folder called "VIDEO" (both folders should be in caps). So, for example. If you had the footage on your desktop the folder structure would look like Desktop->VIDEO->HVR->BlahBlahBlah.M2T
