Not sure I follow you -- are you saying that you have footage on some cards and you want to copy that footage to the FireStore? Just hit "play" on the HVX and "record" on the FS-100 to do that (as long as it's not 720pN footage).
ok, so if i have footage on my p2 cards and want to straight transfer them to the FS-100, i just set the camera up into VTR mode, play the footage and then hit record on FS-100, that sounds pretty easy
