Comment 0 for bug 502426

I just upgraded my Dell XPS M1330 to version 9.10 and since then I can no longer play dvds.

No matter what player (totem, mplayer, vlc, dvdrip) I try nothing works.

The syslog is cluttered with lines like this:

I tried nearly 200 different dvds and was able to play none of them.
