When I bought the Phillips 710, I was told it was multi region. I tried to test it today by borrowing 1 friends Region 1 disk. It played the disc straight out of the box (without any hacks) but only in black & white Thinking that I had to use the remote hacks, I set it to region 1 by remote and found it made no difference. I set it back to region 2 but now it shows an region error code when I place the dvd in. 1) Is there a multi-region hack for the Phillips 710? 2) If the 710 was chipped, surely the remote hacks would not affect it? 3) Why did the Region 1 disk only play in black and white?
