This is very noticable, even on my crappy early 90s crt tv. Small text
becomes unreadable...

Yeah, it's actually amazing how much DVDs suck. BTW for those
complaining about blocking artifacts and such in their lavc mpeg4
rips, guess what? The original DVD has blocking too... :(

The solution? Rent the film cans and use professional equipment to
capture it at hdtv res (or higher) and with 16 bit luma precision,
then make a new codec that allows 16bit luma... Or just be happy with
what you've got.
