I haven't seen the movies you're mentioning... but if you can't see the difference either some settings are wrong, or it's time to get your eyes checked. :-)

I find at this point DVDs look absolutely blurry, and that's using 3 various upconverting players as well as a previous high-end 480i player. I have a pretty large DVD/BD library (160 BDs & 450 DVDs), and I've "upgraded" a lot of my old copies. Every time I've compared the two the BD has been plainly and obviously better, from reduced noise, better shadow detail, much richer colors, and far sharper detail (even on old movies).
