That's a lovely trick. What I don't understand is how the TV locks up
on the correct field mod 2. You are sticking out Odd;Even;Odd;Even...
with the timing info of each being identical. How does the TV know
which to lock up on. If it gets out of sync, the fields will be
spatially reversed, which should look pretty bad (at least on a
true 1080 set).
