What leigh123@linux and s.v.g. said worked for me. But if you have installed what they recommended and are still getting this when you drop in a DVD and Totem auto-starts:
Totem cannot play this type of media (DVD) because it does not
have the appropriate plugins to be able to read from the disc.
Please install the necessary plugins and restart Totem to be able
to play this media.
Here are some simple things to try before giving up:
- Have Totem running and open on your screen before you drop in the DVD. Movie starts.
- Close the plugin warning. Drop down the "Movie" menu. Click on "Open". Navigate to the VIDEO_TS folder on the DVD. Select all of the numbered VOB files (don't select the VIDEO_TS.VOB file) and click on the "Add" button. Movie starts.
- Do step #2 and double-click on a VOB file in the playlist. Movie starts (at that VOB's point in the movie).
After reading the reply below, I decided to play around with several of the media players. I removed all players, related packages, codecs, and libraries that I could without breaking something unrelated (like openoffice which requires some gstreamer packages). I installed the players one at a time along with only the packages needed to play a DVD, and I removed everything again after each test. I liked Xine most, and all it required to play a DVD was to also install the xine-lib-extras & xine-lib-extras-nonfree libraries.
