If you are capturing to a computer, then I suspect your DP was using a Mac and Final Cut Pro. The HVX200 outputs DVCPROHD if you are using the high definition mode. And, you need software that will handle the Panasonic-specific MXF format. Apple converts MXF into its own format for editing. The Firestore just plugs in and captures the video. Then, you copy it over to the computer for editing. The Firestore is the way to go for most mobility and ease of capture.
