Running this through an external DVD drive. Videos app says
DVD source is required to play the file, but is not installed. Hitting play in VLC activates the disc (you can hear it start up in the drive) but nothing happens. I've installed Ubuntu Restricted Extras and libdvdread4 and libdvdcss.
I know varieties of this question have been asked before, but none of the answers I've tracked down are solving the issue.
