Just for clarity I never have and never will download pirated films/software. I know you didn't say that but I just wanted to be clear.
To return to your point, some people are more aware of these issues than others. I live in the UK and our terrestrial (non-cable/non-satellite) DVB broadcasts are horrendously low bandwidth. I have neighbours who cannot see the deficiencies of the image quality.
Some people can hear the difference between 256kbps LAME encoded MP3 and the original source material. I cannot (except perhaps for some "difficult test samples").
I can certainly see the inadequacies of the bit rate used on DVDs and also appreciate the higher resolution of Blu Ray disks. Even commercially produced DVDs have noticeable artefacts (google Edge Enhancement for example) which may or may not bother a viewer (I find them infuriatingly distracting, thank God I don't have a projector). These anomalies are still found on Blu Ray copies but to much lesser extent (read some reviews on http://bluray.highdefdigest.com/
to see the sort of issues that can exist on transfers).
To be honest Blu Ray transfers are generally excellent and it most likely going to be excessive Edge Enhancement, poor source material (those old tape reals aren't always in the best shape), or digital processing. Attempts to remove grain to make things look more polished for modern audiences that are increasingly used to CGI, digital sources, and Pixar films are the biggest problem these days. Oh and I am not entirely happy with grain added to films, but don't mind as long as it is soft.
Anyway, sadly many people cannot see these things. Many people don't play there Apocalypse Now Redux DVDs and see the banding and compression artefacts during the helicopter scenes near the start. For these people DVD is doubtless enough until they get a big enough TV that it starts to annoy even them.
Finally, you mention film sources in a few posts. Have a look at The Godfather box set on Blu Ray or read this review http://bluray.highdefdigest.com/1613...ollection.html
it gives you a good idea about the challenges of a lot of classic source material.
