"Excellent! I used this driver for a JVC GR-D70AA camera and it worked great!
I would assume that it should support USB capture for most of the GR-50xx / GR-53xx / GR-70xx and some other models too.
No installer but just extract the driver from the .rar archive (get winrar, rarlabs.com) plug in your USB and tell windows to look for the driver in the folder you extracted too.
Big thanks to the uploader!"
