I'm new to the HDTV world and I am learning a lot. I understand interlaced and progressive now but what I don't understand is 3:2 pulldown. What is this and what's the difference between this and progressive? My local HIFI store calls the DVD's progressive, and TV's progressive image "Progressive". I thought the TV's line doubler was 3:2 pulldown. Isn't a line doubler the same as progressive? So where does 3:2 pulldown fit in? Thanks!
