Ok, do you actually own a Magic 3.1? Because I have one and I have absolutly no problem swaping disc. I do it on the PS2Reality Mediaplayer all the time. And the 3.1 turn itself off after 90 seconds so I don't understand why you would have problem with DVD region X, but I haven't tryed it so I can't confirm. But there is no hanging problem with the Magic 3.1 and there is no need for a switch on it. And if you ever have any problems booting DVD-9, you could just turn the chip off. But DVD-9 are supposed to boot correctly on the 3.1.
