I have a Panasonic CT-36HX41 HDTV. I have a panasonic DVD-F65 progressive scan DVD player. When I play a DVD on progressive scan, diagonal lines appear as interference on the screen and move from the lower right of the screen to the upper left of the screen. It is barely noticeable, but it is clearly not ideal. Does anyone know what this is? Is the DVD player or the TV defective? These lines do no appear on any of the other devices I use (playstation, Tivo, cable without a box).
