DVD movies do not play with Totem or VLC on a fresh 16.04 Ubuntu install
 

Assume I'm not too bright since I've never claimed otherwise. Introduced to Linux about a week ago and decided to replace the OS on the laptop with Ubuntu 16.04. All seems fine except neither Totem or the VLC install can read a dvd disk or a movie from an external hard drive. Totem simply says it can't read the file. VLC will play the lion roaring in a MGM production, then the screen goes gray and runs with distorted audio. If there is something that needs to be downloaded and/or installed, simple instructions would be much appreciated. I haven't downloaded or installed anything else since some similar posts with possible solutions appear dated.

Sounds like you are missing the codecs.

You might try the solutions given at:

The last one might be most appropriate.

Google is your friend.

Yes "ubuntu-restricted-extras" are probably needed for codecs plus "libdvdcss2" for dvd's. It's a proprietary matter and a nuisance, at the least.

Good information and guidance. DVD and external HD now play. Thank you, J, Fred.
