My JVC GR-DVL815 can not connect to pc

Turn the power switch on your camcorder to "Off." Connect the USB cable that came with the camcorder to the USB port on the camcorder. If you are using the DV cable, connect one end of the cable to the computer first. Put the other end of the USB cable into the USB port on your computer. If you are using the DV cable, connect it to the camcorder. Power on your camcorder. Wait while your computer recognizes the attached JVC GR-D270U camcorder. Typically you will get a pop-up on your screen asking how you want to proceed once the camcorder has been recognized. Open your video editing software, such as Adobe Premiere, Roxie, iMovie or Windows Movie Maker. Import, or capture, the video from the camcorder to your computer using the video editing software. For example, in iMovie you click on "File," then "Import from Camera" to download the movie from your camcorder to the computer.

i lost my original install disk JVC GR-D350as Mini DV Digital Camcorder Driverand i need a web site that lets me install it

USB connection is only for the still photos on the SD card. If there is no SD card in the slot, it will not load.

Video has to be transferred via the firewire cable.

here you go... if you scroll toward the bottom you will see the link to download it for your model

You should have a DV Cable 4-pin to 4-pin firewire (part number VC-VDV204U ) which came with your camera. It would not have firewire on one end and usb on the other. They are two seperate technologies. see http://www.wisegeek.com/what-is-a-firewire-to-usb-adapter.htm

Hi, connect the cam and PC using 4 pin firewire cable (not USB cable).
Switch on the cam.
Open Windows Movie Maker and import the video from device.

Usually that tells you that the driver may not be installed. Remove he camera from the USP or however you have it connect to the computer and try to re-install the drivers with the software that came with it. This is all I could find on your unit at this time.

use firewire cable from your dv port to stream video-4-4 pin for laptop 4-6 pin for mac or tower

a 1394 cable is specified for the GR - D - 270 but the GR - 270 U , not listed ( does your camera use VHS/c , or mini DV tape ? )
