I have a fantastic---to me--hi-def home theater. Itès taken a long time to get it right and until I move on to a dedicated theater room and front projection it will to nicely. However in the evolutionary process I still have a 5 or 6 year old Hitachi Ultrablavk 50 inch. The picture even when calibrated with video essentials or Avia cant compare to the Sony 53 but there must be ways of getting a better picture with it. Maybe a line doubler or something. At first I thought that a progressive scan dvd might be the answer but I have been informed that the progressive scan only runs through the compnent inputs and the Hitachi only has s-vhs. Any recommendations would be great as a secondary system would be nice.
