Hi and welcome to FixYa,
A firewire to USB will not work. It has to be firewire to firewire. A JVC GR-D240ek uses 4-pin, IEEE 1394 compliant Digital Video Connector [DV OUT] to connect a 1394 cable (
also known as a FireWire or i.Link cable) to a laptop equipped with an equivalent IEEE 1394 port. Please note that some laptops firewire port could either be 4 pins or 6 pins.

Soon as that
connection as shown above is established, you can use
Windows Import Video to capture / download the videos.
Other notes (
from the same Windows Help link above) :
- You can also open Windows Import Video by using Windows Movie Maker. After you connect ... your DV camera, and your computer, start Windows Movie Maker, turn on your DV camera, put it into playback mode, and Windows Import Video should open automatically.
- You can also open Windows Import Video by using Windows Photo Gallery. After you connect ...your DV camera, and your computer, start Windows Photo Gallery, turn on your DV camera, and put it into playback mode. In Windows Photo Gallery, click File, click Import from Camera or Scanner, click your DV camera in the list of devices, click Import, and then follow the instructions.
- You can also open Windows Import Video by using Windows Live Photo Gallery. (This options requires you to install Windows Live on your computer.) After you connect your...your DV camera, and your computer, start Windows Live Photo Gallery, turn on your DV camera, and put it into playback mode. In Windows Live Photo Gallery, click File, click Import from a camera or scanner, click your DV camera in the list of devices, click Import, and then follow the instructions.
Verify that the laptop's firewire port is 100% up to specs and totally compliant to IEEE 1394.
God luck and thank you for using FixYa.
Sony DCR-TRV320, Windows Vista does not recognize any input although Firewire IEEE 1394 is connected. Can anyone solve this??? This is on an HP Multimedia PC.
