But isn't more comfortable using the row interleaved stereo mode anyway,
where one hasn't to deal with all of that possible issues? It will have full
screen stereo, windowed stereo, and the TV doesn't even know that 3D content
is present. The only disturbing thing is the eye switch which comes by
moving and placing the windows.

Or do I miss something?
