Back to the 1991 BEN-HUR a second.
Watching it now for the first time on this particular TV, I can see that while there are no artifacts or print damage, the image isn't exactly razor sharp. It's clear; it's fine, but compared to recent DVDs, I have seen sharper images.
To my ears, the sound seems full and expansive. I can't imagine what they might have done to improve the sound field unless they just cranked up the volume or perhaps added more bass. My subwoofer was rumbling plenty with the appraoch of the legions.
However, I haven't gotten to the slave galley sequence yet, so maybe that's not "up to snuff," as they say. I seem to remember watching this some eyars ago that it sounded great to my ears, but that's coming up on the DVD.
