DVD won't play on Ubuntu 22.04.01 LTS

I have been able to watch DVD movies on my 20.04 LTS desktop for several years. Just did an upgrade to jammy jellyfish and this no longer works.

The DVD player works fine with data files but when I try to open it in vlc it responds "no media found".

Did some research and I did do a

sudo apt install libdvdread8

With a legally purchased movie DVD, lshw gives:

*-cdrom       description: DVD writer       product: DVD_RW ND-3550A       vendor: _NEC       physical id: 0.1.0       bus info: scsi@4:0.1.0       logical name: /dev/cdrom       logical name: /dev/sr0       version: 1.05       serial: [       capabilities: removable audio cd-r cd-rw dvd dvd-r       configuration: ansiversion=5 status=nodisc

With a Ubuntu ISO DVD:

No improvement. Has something else changed? I think the key to solving this is the fact that mount does not recognize the DVD's [possibly encrypted] video format although I have reinstalled all of the required packages and they are now at the latest version. I've tried several DVDs, all of which worked previously and work fine on other systems.

My basic problem seems to be that mount cannot read or guess what sort of video file(s) are on the DVD. Mount can read and mount DVDs with garden variety ISO and data file structures. I have done a reinstall of all related packages but may not have done so in the proper order. I had to cobble a procedure from past answers on this forum as 22.04.1 is so new that a complete procedure is not available. An answer that fixes the inability to recognize, mount and read a video DVD along with a complete start-to-finish updated procedure for running VLC to view video DVDs would be hugely helpful to me and to the community.

This may be a red herring but when I log in the GUI shows a floppy drive icon that was never there in previous versions on Ubuntu on this machine. There has never been a floppy drive installed in this machine and there is no entry for it in /etc/fstab or /etc/mtab.
