When I try to play a commercial 4K ultraHD blu-ray movie with VLC,

You can't play a copy-protected UHD disc without a drive with altered
firmware.

Thank-you, Chris.

The blu-ray drive is an LG UltraHD Blu-Ray drive, also labelled (on the box) "UHD Blu-ray WRITER".  Since it is already UHD, I would think its firmware already includes what's needed to handle both UHD and copy-protection.  It does not make sense to me that it needs "altered firmware".

If what you say includes UHD drives, then how do I appropriately "alter" the firmware?

I have a blueray writer as well and I have a whole raft of blueray movies I've bought. These movies play quite happily under Windows using vlc (I believed that was the case but I will need to check that again) so they should play under Linux using vlc. I installed vlc to test it out and after install trying to play the movie produced an error that I didn't have AACS support which was rectified by installing libaacs separately, which begs the question of why did the vlc install not install the libaacs pacakge as well? Having installed libaacs playing the video again complained that it couldn't find an aacs config file, even though I had gone through the vlc preferences and saved the config, and I have downloaded the keydb.cfg file and installed that into the documented folder in the documented case and now vlc is saying it can't open /dev/sr0, and if I mount the blueray device on disc insert and open the mount point in vlc using open disc vlc produces the same error. I have seen in the past that commercial movie discs can't be played in Linux because of codec licence issues, are we still subject to those issues?
