I own a Sony 55HX729. I have cross talk in Hugo when the automaton is featured in a shot. Having bought Tintin, there is zero cross talk in it having viewed about half so far. I believe, too, that cross talk is hardware based but it is odd that some 3D movies are perfect with out cross talk. That being said, i viewed a current model (didn't take note of what model) Samsung 3D at BB today that was being demoed with the Hugo trailer and it had much less 3D than my Sony. The Panasonic next to it seemed dark but no cross talk on either. My TV does have the brightest 3D presentation that I've seen but does exhibit that pesky cross talk at times.
