Can the AV control cables (e.g. Sony Control A1 II / S-link) be 
integrated into mythtv, I've yet to see how?

I think that works over the HDMI cable using "CEC" version 5 technology 
(aka HDAVI control 5) that has yet to make its way into the NVIDIA 
cards.  It works well, e.g. a Sony CAM connected via HDMI is controlled 
by the TV's remote.  Nice.  Shame its not more extensibe.  My AV amps 
are older than the newer HDMI ones, I suppose I could upgrade them ($$) 
but that still would not integrate mythtv.

Complete electrical disconnection seems the better goal, but with some 
really low current device running to turn everything back on.

Thank you.

Yes it didn't take long to work out that the best viewing came from the 
(home) "dynamic" setting, which is the only setting that realistically 
stands besides the best bright LCD's in the current competitive 
marketplace.

Great deals currently available on this TV with Blu ray players thrown 
in.  Some other comments - they do not take 1080p via component but do 
over HDMI, most peers of a similar standard do both.  Their website also 
says the TH-P42V20Z Power Consumption (Normal Use) is 139 W and Power 
Consumption (Standby) 0.4 W (Great if that is what it is?) however the 
back of the unit says 1.8A, which is ~423W, presumably peak power 
drawer.  What is normal use? The most cut down dullest mode showing all 
blacks with no sound?
