Reply #35: That really depends on where your display is.

Yeah, if your set is 100 feet away from you, it might be difficult to discern the difference in resolution between DVD and Blu-ray. Otherwise, I think the difference is a tad clearer than day and night. DVD has only around 400,000 pixels on screen at any given moment (half that if watching on an interlaced display). My computer's desktop runs at 2560x1600 which is just about 4 million pixels on screen at any given moment, that's 10x the resolution of DVD and believe me, I notice the difference. Blu-ray's max resolution is 1080P or about 2 million pixels (5x that of DVD). Now, while the difference between 720P and 1080P might not be very noticeable except for on large displays (50" and higher), the difference between 480P and 720P is very noticeable, even on smaller sets, so long as you sit less than 15 feet or so from your display. If DVD resolution is sharper than you're capable of seeing, you need to get an eye exam badly.
