Depends, most people can't even tell when they're stretching a 4:3 program into 16:9... I'd say probably a further 25% can't tell a quality difference between VHS and DVD, 95% of people don't see macroblock artifacts in DVD video and 100% of people in sports production can't see a difference between lower-field dominant, 4:1:1 DV footage and upper-field dominant, 4:2:2 Beta footage.

Most people don't notice quality. That's why country albums sell.
