BDR-X13E-S or BDR-X13E-K

Do I only need to worry about the drive if I want to rip 4k? Or is blu ray also included? And I guess on that vain dvd as well?

If these drives are no good for even blu ray are there any good alternatives?

Also seen some mention of BW-16D1X-U

Though it needs to be flashed

In February 2023, Pioneer updated their firmware to disable LibreDrive support, which is necessary for ripping 4K UHDs.

Pioneer firmware update February 2023

Without LibreDrive, the drives will rip DVDs and regular blu-rays but not 4K UHDs.

Your best bet is to buy a Pioneer drive from a seller in your region. They can still source new drives with old firmware that'll work with MakeMKV.
