The 3 patches to libdvdnav in the thread http://comments.gmane.org/gmane.comp.video.dvdnav.general/1658 did apply successfully, but I still crash at the same place. None of the debug messages mentioned in the patch appear anywhere in the trace output. I also deleted ~/.dvdcss but that didn't help.
There's also a patch to livdvdread in the first post of that thread, but I didn't apply that as I'm seeing the crash in libdvdnav. If you think I should try that also, let me know, and if you want to arrange some way for me to get you the ISO file I will. Also going to try using DVD Shrink 3.2 in a Windows VM to shrink to a DVD5 and see if that rewrites the nav code enough to make this playable.
