Pio 436XDE and OPPO 971H problems

Hello

Has anyone else had the following problems with a 436XDE and 971H using HDMI

1. The player keeps setting itself to NTSC. I've set to Auto and am using PAL Region 2 discs but still it wants to output at 60Hz NTSC.

2 At 1080i and 576p, which both show as 1125i on the Pio, I can see extremely visible horizontal lines. Is this a fault with the display or the player or is this just how it is? I hardly notice this effect with Sky+ which shows as 625i over RGB. I have actually seen this same effect this strong on only one program, Dragons Den.

Can anyone help?
