The VLC player cannot play a DVD disk on my computer. Whenever I click the menu "Media > Open disk..." from the player or "Play with VLC media player" from the context menu, the error prompt "Cannot play a non-UDF mastered DVD" is shown as below:

I tried KMPlayer and it had no problem of playing. I have installed `libdvdcss-1.4.2.tar.bz2` and `libdvdnav-6.0.0.tar.bz2` as per the instruction of this [article](https://www.5kplayer.com/video-music-player/solve-vlc-cant-play-dvd-problems.htm) via the Ubuntu shell on Windows 10 by entering these commands:

```
./configure
make
make install

```

but I'm not sure if the libs got installed correctly because the same error recurred after restarting VLC. I tried to Google the problem as well as searching the [forum](https://forum.videolan.org/search.php?keywords=cannot+play+non-UDF+mastered+DVD&sid=f9b65c30a427c7d78499100f32a87820) and here on this site and didn't find any related discussion. I don't want to convert the DVD to formats other than an ISO image because I want to preserve the DVD control while viewing the videos in it. I did make an ISO image out of the DVD disk with [ImgBurn](http://www.imgburn.com/), and it's the same problem with the image when played with VLC.
