I have an old Panasonic DVS15 video camera and several tapes I wish to edit. Neither my newer Windows 8.1 or an old XP system recognises the camera in Movie Maker using either of two firewire cables. The output from the camera to a TV is OK. Is there any way of checking if the camera is generating a firewire output, or any suggestions for a solution. Panasonic no longer have any reference to the model on their website. The original software (?) was DV2, but I have no recollection of any installation disk(s).
