What’s the actual reason for older drives not being able to read UHD/4K discs?
I’ve known about this software for years and used it maybe 3-4 times on regular Bluray discs with my BH30N and CH30N, but all the research I did says these 2 drives will never do UHD, and I’m just curious as to why that is. Those drives are MT1939, so I know they can’t do it, but why? Is it a capability of any 1 chip, are there any physical differences in the drive like the laser, etc, or is it just a firmware thing? What is the actual and/or physical reason for the lack of UHD support in drives before around 2016? Also what is the drive platform anyway, like what part of it?
Not trying to demand support or change or anything given that it seems it just can’t won’t happen and I’m pretty thankful people tinkered away for years to make all this possible, I just want to know what is preventing older drives from having UHD capability.
Thanks.
