I'm unable to play "Transformers 3 - Dark of the Moon" with what looks like a similar failure, whilst Movie Player is able to play the disk (Totem 3.0.1 with 0.10.35 gstreamer on ubuntu). Version info for vlc and libdvdnav and log below. cefn@cefn-dell-oneiric:~$ vlc --version VLC media player 2.0.0 Twoflower (revision 2.0.0-0-g421a4fc) VLC version 2.0.0 Twoflower (2.0.0-0-g421a4fc) Compiled by buildd on nannyberry.ppa (Mar 3 2012 01:06:44) Compiler: gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) This program comes with NO WARRANTY, to the extent permitted by law.

Here's a console log from the GUI when I try to open the DVD direct (similar experience with an iso image). I upgraded to a newer VLC version using ppa:bdrung/backports. That gives me libdvdnav 4.2.0-1~oneiric1~ppa1 which I've combined with vlc 2.0.0-6~ppa1 . Trying to play the video gives the log below with the last lines, (or very similar lines) seeming to run forever and ever. cefn@cefn-dell-oneiric:~$ vlc 2>&1 | head -n 100 [0x9450920] main libvlc: Running vlc with the default interface.
