Getting the Panasonic PT-50DL54 which has " Progressive Scan Doubler (enhanced)". What exactly does this mean? Also, how will this tv handle a) a basic progressive scan dvd player connected via component, b) an upconverting progressive scan dvd player connected via component, c) both a & b connected via hdmi? To be more specific, can/should I shut off the progressive scanning of the tv or the dvd player because one is doing a better job than the other? Sorry to be asking so many noob type questions about this but I can be pretty anal about this stuff and I like to make the best out of the hardware I get without any confusion when setting up and configuring. Thanks, Steve ps: is avia still a good tool to use with a tv such as the one mentioned above? if this is not the right forum for these questions please move.
