I recently prurchased the new 1080p 50inch Samsung DLP. Very happy with it so far. The only issue is while watching DVD's I have 2 sets of lines that move up the screen. This does not happen on any of my other inputs, any ideas?
You've got some kind of ground issues. Is the DVD player plug into an extension cord? Have you swapped your video cables around? The power supply on the DVD play could be bad, plug it into another tv.
