With the new DLPs, such as Samsung with its latest light engine and other updated gizmos, do I still need a video processor, such as DVDO IScan+, to improve the video; or do the new TVs, with their updated gizmos, provide similar video processing capability as if I connected a separate processor like the DVDO IScan+? In other words, with today's latest TV technology, am I wasting my money by buying a video processor such as the DVDO IScan+? Thanks much for the help.
