Tried to play a DVD on my Vero 4k today, but to no avail.
OK, checked installed packages and install libdvd-pkg (and libdvdcss subsequently) as well as libdvdnav4 and its dependencies. Nevertheless - the DVD won’t even display a single second, a menu or anything. (AVATAR)
Other DVDs are playing fine, e.g. SKYFALL
How can I figure out what is the cause of this?
