Is there anything non-obvious to consider if I want to remove the AC3-RF module from my AV32R-DP? As far as I can see, there's only one nut to unscrew and 2 plastic standoffs to undo. Does anyone know the 'secret' key codes to disable/enable the module, or will its absence be detected automatically? Is it possible to replace the AC3RF with a conventional coax SP/DIF input (not as a factory option, obviously, but can it be hacked, e.g. by connecting some pins on the mainboard's connector for the RF-board)?
