I have seen this on many sets including my Samsung 30" widescreen DTV. The effect appears to be visible even when using the component video input. I believe it is caused by signal reflections in the chain of things between the signal source (e.g. DVD player, etc.) and the DTV input.

While I am not aware of any technical specifications for the acceptable intensity of the shadow image, in my experience, the intensity of the shadow image and the distance from the original image seems to depend on the video cables that I use. I tried several different kinds until I found that the Kimber PBJ (copper, not silver) Audio cables worked pretty well, with low noise and low level of reflections. What you may have not noticed also, is that there are several shadow images. One set may be so close to the orignal image, that you may have to look very closely to even see it. Another one is the one you see 2cm away.

If you haven't already done so, I would recommend trying different cables until you find the right one. And cost does not appear to be related to performance here, as far as I can tell.
