I can not play a DVD movie with VLC.

I am using verion 2.2.2 Weatherwax.

Which DVD? I know I can't rip one of the Generation Kill DVDs I have to my HDD no matter how hard I try. Is the DVD damaged? Is it different in some way? Does anyone else have the same thing on DVD to test?
Sadly, I think you may need to purchase another copy. If that doesn't work then something is afoot...

You've been here long enough to know to provide details when asking a question. You don't tell us what version of Ubuntu, don't tell us what error(s)/message(s)/behavior(s) you're seeing, what you've done/tried, or even if this has ever worked at all, with ANY DVD. So what do you think we'll be able to tell you?

The very first hit in Google (past the sponsored link), is:

...from the Ubuntu forums, telling you what to install to play DVD's with VLC.

CHill out bro. Life is too short to get stressed.

VLC gives NO error message.

When I try to open disk, nothing happens.

My distro is on left side of every post. Version 16.04

And I have already installed the library shown in your link.

Not stressed at all. And instead of junk like that, try "Sorry, I should have posted details". And I'm certainly not your "bro"...wouldn't be too happy if I was.
Really??? Did you try starting it from a terminal window vs. the launcher? Because that WILL return messages.
And how many people have MULTIPLE distros listed on their profiles/"left side of every post"??? How are we supposed to know what machine you're talking about, exactly?
And we can't know that unless you tell us.

So we're back to "there's no way to diagnose this issue, since you haven't given us anything to work with". Just saying "nothing happens" gives us no diagnostic information at all. Try starting VLC from a terminal window in X, and watching what happens when you insert that DVD. And again, has this EVER played a DVD, or is this a new issue??

Output from CL
Do not know if laptop ever played a DVD.

HP G60 is laptop.

I un-installed and re-installed VCL and required libraries.

Now my DVDs play.
