Regionset fixed it for me. I was only noticing the problem on some DVDs. My PC is home built and I had not set the region when I first built the system. Most DVDs worked ok. A few had issues which matched this topic.
Setting the region code seemed to do the trick. :-) I found this link useful too: https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs#Setting%20DVD%20Region%20Codes -- Cannot play DVDs - Could not open location; you might not have permission to open the file https://bugs.launchpad.net/bugs/342890 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
