App worked as advertised though I feel it put a little too much color in the picture so i turned that down just a touch. Overall i feel my picture quality is greatly improved from the "cinema" setting on my panny. I am sure a pro calibration would be much better but for free I can't beat it. I use audyssey for audio so not going to throw the 50 bucks for a cable. If anyone does try the audio feature please let us know your results.
