My Sony KV-34XBR800 has three DRC modes as follows: INTERLACED - Recommended for moving pictures PROGRESSIVE - Recommended for still images & text CINEMOTION - Reverse 3:2 Pulldown Being new to HDTV technology, I am really not sure which DRC mode to use when... or how these modes enhance the picture ??? Is there one mode that is better for: a) Analog signals b) 480p or 720p cable or antenna signals c) 1080i cable or antenna signals d) 480p DVD I have switched between modes when watching both over-the-air antenna signals and DVD movies, and I don't really notice any difference. Can I get some suggestions on how to use this video feature ???
