I recently bought this player for dual prog scan, which I now find is done anyway by the new plasma. When the player is set to output prog scan, I am sometimes getting black lines within the picture. The player appears to have quite a few settings for prog scan output i.e. off, on, auto 1, auto 2 etc. Will any of these cure this line problem or should I just switch it to interlaced as I have no idea why there are so many choices, that is unless I need to make some other changes. Any help to explain the various settings would be greatly appreciated.
