Weird problem started just today. My OpenSUSE 12.1 Gnome box is used as a media PC and I rip my DVD collection to it. Today, I pop in a new DVD I bought and got an error “Cannot mount [DVD_name] - Authentication is required.” The DVDs have always mounted automagically before, so I don’t understand why this suddenly started. Now, here’s a weirder part, if I reboot the machine WITH THE DVD IN THE DRIVE, then the DVD will be mounted and accessible when I login. However, I cannot eject the DVD from Gnome (I get the same error: “Cannot Eject [DVD_name] - Authentication is required”), I have to press the button on the drive itself. If I want to access another DVD, I have to reboot with it in the drive which is an obvious hassle.
Thank you in advance as always for any help y’all can provide!!! I will post the output of anything you need.

did you have any updates, application installed, changes in hardware,
freeze, errors, power flux, config changes, or etc on yesterday (or
between the last time it worked right and today)?
So, do all DVD’s do this are only this one? I ask because this summer I did buy one movie that Kaffeine would blow up trying to read. After further looking, seems like it has some strange attributes like being bigger than a DVD can be. After looking through the internet about that movie it seems like this was an attempt to keep it from being copied. It did work OK using VLC, however which I guess did care how big the DVD claimed it was.
As James has already asked, it is important to know whether this relates to one particular DVD, or all data CD/DVDs. If the latter, then it may be due to some update affecting the active polkit policies.
I did perform some updates but I didn’t pay attention to what they were. I saw the update notification and then ran “zypper update” to bring everything up to date (I prefer updating via command line rather than GUI).
It was a few days after that before I attempted to access/play/backup a DVD but the next time I tried, I got that error.
One thing I failed to mention (not sure why, really) is that I’ve been trying to access the DVDs while logged into my main account (“htpc”) through NX over the network. This computer is my media PC and it’s “monitor” is an LCD projector hanging at the rear of my living room. I use NX from my laptop to perform tasks such as backing up my DVD collection to avoid turning on the projector and shortening it’s bulb life. I use the “htpc” user for both the console and NX.
I just tried accessing the DVD drive from the console (projector on) and I am able to access it fine! I had a similar problem when this same PC was loaded with Mandriva 2010.0 and it ended up being a PolicyKit issue. The difference there, however, is that with Mandriva, I had a separate user set up just for NX. I still had to make a PolicyKit change for that user though in order to access the drive. I’m going to go dig up that info and see if it’s applicable now for OpenSUSE.

Makes sense, the local user has access to the drive; the remote user not,
he is not at the box.
You can use manual mounting, though.
