You know more about this than I do.

Not thought about it..maybe web/html based config & control. Maybe run
web page based myth frontend served from BE.
You did say shame it is not more extensible...

I don't trust Sony specs & this link does not clearly state the
capability. I bet it will not do 1920x1080p or 1920x1080i over
component/VGA.
Sony would be the last TV expected to do this..

Direct pixelmapping & no overscan & able to do 1080p so full
de-interlace capability of GPU/video card used.
HDMI will let you do 1080p50 or 60 so video card can de-interlace.
The nvidia feature set C is still better than V20 (IMO).

1080i60Hz is not right should be 1080p60 or i30. 3D NTSC blueray/ might
be 1080i60.

You should not be using 30 or 60 for NZ recordings as you will have
euro-judder &/or possible weird effects from confusing the TV into
inverse telecine or other...
TV recordings should be using i25 or p50 except for NTSC DVD etc..

nvidia feature set C inverse telecine is very good (Pink Floyd The Wall
DVD).

I did say my guess & but there is some method with the madness....
