I recently replace my 20+ yr. old speakers with Klipsch. I think they are B3's. Of course that led to a Yamaha receiver which obviously meant I had to replace my old dvd player with a new Sony Blu-ray player. I'm still going to use my 57" Sony rear projection hd tv. It has a great picture, but of course nothing like the new flat screens.It's a 1080i tv. Isn't a dvd 720p and a blu-ray 1080p? It seems to me that a blu-ray would look better on a 1080i tv than a dvd. The reason I'm questioning this is that a friend said that with a 1080i tv, there wouldn't be any noticeable difference. I know, dumb question. Any help would be greatly appreciated.
