I ran into the same issue, getting the "ifoRead_TITLE_VOBU_ADMAP vtsi failed" message with I think vlc, and an assert failing in libdvdnav with totem. The Planet Earth DVD I was trying to play was region 2+4. It played correctly on my Windows install that had an older version of vlc. I tested several other DVD's in Ubuntu with vlc, and they all worked correctly. They were regions 0, 1 or 2. Next I tried the Planet Earth DVD again, and it magically worked. After rebooting it still worked.
