Try with gstreamer gst-play-1.0 /dev/sr0 or gst-play-1.0 /dev/cdrom Is he played well?
Hey Anthony, thanks for your timely reply and suggestion! I wasn't able to play the DVD in any player. I started looking around and found out about "DVD regions". I'm from Europe but live in the U.S. - once I changed the region and I was immediately able to play the movie in VLC player. Dragon Player no longer segfaults but still doesn't play the video (but GStreamer doesn't play the movie, but it's beyond the scope of this ticket/KDE team). Therefore, we have one confirmed bug here: if the region of DVD device doesn't match the region of DVD disk, Dragon Player segfaults. === Just a FYI. Not seeking help with this. Gstreamer doesn't play the DVD: --- nowaker@nwkr-laptop ~ % gst-play-1.0 /dev/sr0 Press 'k' to see a list of keyboard shortcuts.

Phonon is just a warpper around gstreamer library, dragon is a graphical representation of Phonon, so you have 2 choices: 1. sudo pacman -S gstreamer-vaapi libva x264 x265 2. sudo pacman -S phonon-qt5-vlc (vlc backend for phonon, systemsettings -> multimedia -> audio/video) In 2 cases it's better to provide vainfo result because of missing h264 decoder. sudo pacman -S vainfo
Thanks Anthony. Using VLC as a backend works fine. Gstreamer doesn't seem to work although everything seems to be in place for it.
