Laptops partially fixed this issue - you can just skip the bad parts. Higher end dvd players used to do the same, but players are a vanishing breed and consoles are not much more than dumb players usually. Ofc it would be nice if there were just no skipping - there were a number of technologies being employed back when DVD was the pretty much the only format in town, I suspect the data redundancy may have been traded for cramming more features on a disk. Back when ripping (my own) disks was a thing, you could compress a movie to half its size on disk (no coded compression just more intensive picture compression) and burn it twice to the same disk... Ofc the problem with that was the consumer burnable disks use a degrading chemistry unlike stamped copies, so they would last 3-4 years before undergoing significant corruption.
