I highly doubt JVC has created Windows 7 drivers for an older camcorder such as the GRD-73. And I'm assuming non of the generic packaged drivers worked, since you probably wouldn't be posting here. However you can attempt to locate them using
this tool. It may be able to find you a compatible driver that will allow you to use the device with Windows 7
