DVD sales from how long ago?
I don't particularly care for the way that most of the major studios treat their catalog product either, but it is a fact that movies like Pal Joey, Picnic or The Way We Were do not sell well on Blu-ray. They just don't. The primary audience for these movies is older viewers, who generally are not as fussy about the difference between DVD and Blu-ray, and don't like having to re-buy movies they already own on one format.
It's hard to agree or disagree with the statement that those titles don't sell well on Blu-ray when they were never available at "regular" prices. While as a former film collector my collector's mentality FORCED me to purchase those titles, even though they are grossly overpriced (between 29.95 and 34.95 + oppressive shipping costs).
What bothers me is that they seem to quickly transfer real garbage to Blu-ray, so it's no wonder that sales are down....according to "them". As I've said before, if they would transfer REAL blockbusters from the 50's, 60's and 70's, to Blu-ray in a timely manner, maybe the customers would still be alive to buy them. If you ask me, this is just part of their agenda to justify eliminating DVD's and Blu-rays so they can sell nothing but streaming. All I can say is good luck to them.
P.S. "The primary audience for these movies is older viewers, who generally are not as fussy about the difference between DVD and Blu-ray, and don't like having to re-buy movies they already own on one format."
I GUESS I'M ONE OF THOSE OLDER VIEWERS YOU'RE REFERRING TO. FYI, some of these titles I'm on my 3rd and 4th copies before FINALLY getting a Blu-ray. And in many of those cases, as I'm sure you're aware, the Blu-ray was (and still is) defective. I also probably have the distinction of having the LARGEST defective Laser Disc Collection in the U.S.
