Forgive my ignorance on this issue, but I recently purchased a Samsung 4061 LCD and love the PQ, but am having issues with PQ on DVD playback. Using a regular (480p) progressive scan DVD player, lots of dark scenes on DVD look terrible in terms of noise/grain/etc and the color doesn't look quite right.I'm guessing this is related to the TVs poor upscaling of the 480p image, so I've been looking at good 1080i/p upconverters. My question is this, how close can an upscaled DVD on Toshiba's A3 (in 1080i, then deinterlaced by the TV) look vs. a SD-DVD on a regular tube TV? I always thought DVDs looked great on my CRT, and want to get as close to that (or better) without having to buy actual HD-DVDs or Blu-Ray titles...Also, would the A3 even be worth it if my set has to deinterlace that signal because it is a 1080p panel? Should I be focusing on upconverters with a 1080p output?
