Thank you for your e-mail regarding Denon Products.
You can download the current version software for the RC-8000/RC-871 from the following Denon American site :
www.denon.com this will explain the procedure for the download. You will need to purchase an A to B USB cable from youre your local P.C. retailer. This will give you the editing suit, and is compatible with the RC-871, but is known as RC-8000 at this present time Denon UK does not have its own version.
