I have a Benq dw-1655 OEM. After I first installed it I started searching for a RPC-1 firmware but when I ran Nero Infotool, It shows that it's already RPC-1. I uninstalled DVD Region Killer to see if maybe that was causing a false report but it still reports as RPC-1. I've tryed all my Region 2 and Region 3 DVDs and they all work. Is there any idea why thats the case?
