My DVD Collection: What should I upgrade?

[ezeblazin]

Alright, I have recently become a Blu-ray addict, and am wondering which titles in my DVD collection(that are available on Blu) are worth upgrading. I'm more concerned with picture quality than anything else. So basically, movies where the picture is much better than an upconverted DVD.

I did some initial searching on this site, and judging by revews and User ratings, this is is what i'm thinking so far. Please give feedback, and let me know what you agree or disagree with.
