I have a full HD tv 46" with sony 350 blu ray player. Excellent picture. I took my blu ray player to parents and played it on their panasonic plasma 37" which is only HD ready, 720p. The picture seemed exactly the same as a normal DVD. I didnt tell my dad we were watching blu ray and he actually said "the picture is a bit naff". My brother saw it playing on my full hd tv without knowing it was blu ray and he commented what a great picture. When we played it at parents he also said there is no difference from a normal DVD. So my conclusion whats the point unless it is full HD tv. Makes hardly any difference on a 720.
