</div>The only suggestion I can come up with is in the past with 'weird'<br>
problems of playback to check what dvd device is being pointed to in<br>
the settings. i.e. /dev/dvd.<br>
<br>
Note I have kubuntu 9.10 installed on a separate partition and am using<br>
ubuntu 9.04 here. This works fine but I have issues with nvidia and<br>
9.10 that I have not solved yet. One thing I am going to try is using<br>
the xorg.conf file from 9.04 for the 9.10 installation see if that<br>
helps, but I would check your /dev first. Had lots of problems in the<br>
past because of that not being named correctly. (and no sorry, I don't<br>
know what it should be) mine here according to vlc is<br>
<br>
/dev/sr1<br>
<br>
which I am surprised to find. But vlc plays everything without<br>
problems so...<br>
