Let me start by saying that I have done a search and dug through what information I could on this forum. I also have some knowledge about progressive playback and deinterlacing issues, but on a recent trip to a local dealer with my friend (who was looking at a sony 46wt510) I was blown away by what I saw and heard. I appreciate anyone's input on this, since I haven't had any experience with progressive displays. First we noticed that there were jagged edges everywhere in the demo disc (not a film, lots of slow pans). My first instinct was that this must be an interlaced source, and what we were seeing was incorrect deinterlacing. We asked a rep to come over and talk to us, and when we brought up the jagged edges he immediately took the dvd player out of progressive mode and turned on DRC. The change was astonishing. No jagged edges, beautiful picture, you get the idea... The kicker was that he told us that the shop as a whole frowns on progressive scan as a flawed technology, and they suggest running all dvd players in interlaced mode, using DRC to upsample to 960i. Unfortunately the Sony is slightly out of his price range (but he wants that size display), so I would like much more information before considering lesser models. So my questions are: 1) Would a better dvd player (like one equipped with a Sil503 or DCDi) be able to play that source without jagged edges in 480p? And then would it look better than DRC-960i? 2) What are the drawbacks of always running interlaced? Is it common for dealers to recommend this? Does the interlaced chroma error become a major issue? 3) Is there an analogue to DRC from other manufacturers? Would a budget RPTV look far worse in interlaced mode because it doesn't have DRC or a similar feature? Thanks for any advice. I know I'm asking for a lot. Please help!
