This is not a duplicate of Why does DVD playback still not work after installing libdvdcss2? as the answers there are not valid for 16.04
I've reveiwed https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs
and installed the libdvd-pkg with
sudo apt-get install libdvd-pkg
I've checked that the region is set:
sudo regionset /dev/sr0 regionset version 0.1 -- reads/sets region code on DVD drives Current Region Code settings: RPC Phase: II type: SET vendor resets available: 4 user controlled changes resets available: 4 drive plays discs from region(s): 1, mask=0xFE Would you like to change the region setting of your drive? [y/n]:n
I didn't change as it's set for:
Region 1: U.S., U.S. Territories, Canada, and Bermuda. which should be correct.
I double checked that the package is installed with
$ dpkg -l |grep dvd ii dvd+rw-tools 7.1-11 amd64 DVD+-RW/R tools ii dvdauthor 0.7.0-1.4 amd64 create DVD-Video file system ii libdvd-pkg 1.4.0-1-1 all DVD-Video playing library - installer ii libdvdnav4:amd64 5.0.3-1 amd64 DVD navigation library ii libdvdread4:amd64 5.0.3-1 amd64 library for reading DVDs
I even went so far as to issue the command.
sudo dpkg-reconfigure libdvd-pkg

A picture would have been better above but you get the idea. Output was:

The drive recognizes the insertion of the disk And the title shows up in Nautilus and totem but attempting to play in totem results in "Can't Read DVD" The same drive reads CD's flawlessly and the same DVD plays perfectly in another system. this machine was an upgrade from 14.04 but on 2 other systems that were installed fresh with 16.04 I have one that exhibits this problem and another that doesn't.
EDIT: I tried deleting ~/.dvdcss folder. No help although there were some keys stored there. and while the documentation here was informative no amount of playing with the environment variables for decryption resulted in success.
