Thanx for a great review, I own the HD83(00)myself and am absolutely taken by its PureMotion Frame Interpolation. Where I beg to differ is that in the high FI mode it doesn't add "digital effects", what it does add is reality. The problem WE are having, is that since the day we were born we've all gotten used to the motion blur in theatrical films and on home video. But our eyes can do much better and in reality capture movement vastly exceeding 24 frames/sec.

Douglas Trumbull first noticed the problem and introduced 30fps for the showscan theme park rides, filmmakers like Peter Jackson and Jim Cameron are investigating possibilities to overcome the limitations of our now almost a century ancient camera filming process with only 24fps.

Thanks to the PureMotion FI details, previously obscured in motion blur, suddenly become noticable, especially objects in foreground that are out of focus, providing valuable information to our brain for a better depth perception of the overall picture and scenery. The scene from ALIENS where the aliens break into the command center almost looks 3D in 2D and the scene from CRIMSON TIDE, where water breaks into the engineering section, made me want to run to the kitchen to fetch a water bucket for all the water I was expecting to drop from my projection screen.

We are now watching scenes exactly like the filmmakers watched these while they were shooting, but we will also notice limitations of the studio sets and certain CGI (LotR: Battle in RETURN OF THE KING). Purists and those that have gotten used to the motion blur will probably reject FI, others that have been annoyed by the motion blur (especially ever since these awful handheld, shaken camera movements became fashion) will welcome the PureMotion FI the HD83 provides with open arms.

Since "digital effect" has such a negative connotation (Digital Noise Reduction etc.) I felt it necessary to elaborate on the issue and apologize for my lengthy post.
