this is a great topic, i personally use canon FS-100 that records footage in AVCHD(m2ts, mts, ts file), becuase i am a reporter, i need to cut and paste a few miuntes worth of file for TV report, and i use FCP, but many times the FCP just refuse to take AVCHD file, i serach around on the net and finally find the AVCHD import FCP
