What kind of new tv did you purchase? Obviously, the better tvs will see more of a difference between Blu-Ray and regular DVD.
I bought one the other day and it is clearer than normal DVD's but I only have a 720p HD TV so the difference for me isn't that aparent. The upscaling thing isnt that noticable especially with older films.
All my new films will now be bought in Blue Ray and maybe I will upgrade some of my favourite films in the future. The problem is with HD TV's is that it makes your old films look shit where they looked fine on a standard TV so making you upgrade them to Blu Ray.
The TV says 1388 X 768p resolution on the box. I'm not sure what that means to be honest. Is that good? I did ask as I was paying for it if it would be good for Blu-ray should I decide to go that way, and they said yes. Can someone explain to me what the "upscaling" thing is about? I'm not familiar with that concept.
