The bottom of the image, when playing 2.35:1 DVDs on my Sony 34" XBR800, is higher at the center than at the edges by a good 4-5 mm (I measured it)... essentially forming an upside down smiley face . The upper right corner of the image also curves downward by about 3 mm. I posted on this problem earlier and was initially blaming my new Denon DVD 1600 player, but recently confirmed the DVD player was not at default by duplicating the same problem with a Toshiba DVD player. I guess I am just curious if any other Sony owners (particularly the 34" widescreen sets) have experienced the same problem ??? And have you been able to correct the problem ??? I am now considering a professional calibration, but I am not sure this would fix the problem either. And if a calibration did fix the problem with 2.35:1 DVDs, would it end up causing a smiley face curve or different distortion on other formats (1.85:1, 4:3) ? I am not too crazy about spending the extra money for a professional calibration, particularly since I am otherwise happy with my own basic calibration using the AVIA disc.
