A lot of that older stuff was filmed on 16mm or less so it wasn't great to start with so capture to full HD is perhaps not worth the effort. Spending the time to do a pan and scan on something that so few can hope to appreciate (due to not being able to comprehend the historical context) is a fool's errand.
Probably correct. So I doubt the George Burns and Gracie Allen Show will ever be in HD . That is why I need a good TV set that will match at least what I have in SD. I could care less about 4K. HD is okay, but to me I would rather have access to an old shows in poorer quality than not have it at all.
