I was having problems with RPC so decided to remove it!
I tried using any of the versions of the firmware for my AD-7170S and they all refused to play DVD’s via windows Vista. Only when I went back to the original did they start to play again. They all complained about resolution or incompatible connection (I’m using VGA and not a HDMI connection so it shouldn’t be any DRM rubbish)
Is there a problem with the RPC code? I realise they are fairly new drives - any help would be appreciated - the region coding is driving my wife nuts!
