Okay guys, I have a Denon DVD-A1 and as standard it is Region 2. Now unlike companies like Arcam who actually build their machines as Multi-region and then use handset hacks to control the region, this one is programmed to be Region 2. Like most UK owners I have had my machine upgraded to Multi-region, but where does this software come from? Are there different people creating different versions of multi-region mods? How do I ensure that the multi-region mod is not going to cause problems with the firmware on my player? As always, your thoughts please. Ian.
