Default Problem connecting Pioneer VSX-S300 to Nvidia Ion - flat panel scaling solves it?

Dear all,

I am trying to connect an Zotac Nvidia Ion motherboard to my new Pioneer A/V through HDMI.

While the hdmi connection works flawlessly when I connect it to my LCD directly, when I connect it to the Pioneer A/V I don't get any sound our video, even though:
1) The A/V's "hdmi light" is on, meaning it has established an hdmi connection
2) If I turn the pc on and let Linux boot, I won't get any sound or video. But if I then switch the connection to my LCD directly and look at NVIDIA-settings, it lists the "Pio VSX-S300 (DFP-1 on GPU-0) (with correct model!) in the "display model" ...so it is recognising the device

While I was fiddling around with the settings I managed to make the system work:
1) I went to DFP-1 (Pioneer...) in nvidia-settings
2) Unchecked "force full gpu scaling" in "Flat Panel Scaling"
3) Switched the hdmi cable over to the A/V
4) Presto! I had sound* and video

The problem is that if I restart, I lose the image again. And if I switch back to the LCD, I see the "force full gpu scaling" is again checked.

How can I make this permanent? I tried adding FlatPanelProperties" "DFP-1: Scaling = Native;", but I must be missing something: when I restart that setting is not applied and nvidia-settings has the checkbox checked.
I attach my current xorg.conf file.
I appreciate all the help with this!

* Actually the hdmi sound in 5.1 configuration is wrong: the speaker test is not right, as some speakers are switched (eg: the centre speaker test outputs in the left back speaker, or the right back outputs in the subwoofer)...but I'll get to that once the other problem is solved!
