Apologies if this has been mentioned elsewhere, but I've had a hunt around on this Forum and I can't find an answer. Anyway, I've just bought this from Ebay: OPPO BDP-103 105 USB Region Hardware Kit If you click on and enlarge the second image, it shows that it's an external solution that requires you connect one lead to the RS-232 port and the other lead to the USB 2 port. You then use the remote to key in some commands and specify your desired Blu-Ray region before playing your disc, so it seems pretty straightforward. What I'm unsure about is: 1. How safe is it to have a circuit board exposed like that? 2. Should I cover it up with some duct tape or will that make things worse? 3. Has anyone bought this item and used it? Any issues? Thanks!
