The picture this combo's DVD player produced was "hot" in a couple of ways. The maximum-white-level error was very high, which is likely to drive a picture tube into various types of misbehavior on very bright areas of an image. This can be corrected using the TV's contrast control in conjunction with a DVD test disc. There was also a large boost (the highest we've measured) in the midrange of the luminance frequency response, which produced a sense of hyped-up picture detail. Turning down your TV's sharpness control may produce a more accurate picture. The CD performance was good if not stellar. - David Ranada
