See if you can import this raw .MTS file
http://jay-rock.com/00000.MTS into FCP by itself and edit it without its orginal directory and coexisting files.
I have a client that cannot import this format without the entire directory structure in tact so if you remove any files from the same folder it shows up as corrupt.
I am on a PC with Premiere CS5 and I can use these files even without the directories or other files. Im not trying to give him everything what was on the card because there was other content in the same folder. Do all MAC FCP user have this same issue and what is the possible solution if that is the case.
