The Panasonic PV-GS9 miniDV camcorder uses USB only for still images. Like just about every other camcorder, it requires a FireWire connection for video. Panasonic's manual lists the cable as "optional." As such, it may be a separate purchase. Panasonic refers to the optional FireWire cable as a "DV Interface Cable." I strongly suggest that you pull out your camcorder's manual if you still have it or download it from Panasonic's website if you don't.
Thanks for info...have firewire cable and have gone through camera manual...my imac running os x 10.4 does not read that the camcorder is there..was hoping there was a program out there to purchase that would solve problem...
