 Here's the story.  The DVD has 99 title tracks, and ten of them have invalid IFOs on them.  The invalid ones are 2 through 8, and 36 through 38.  The bogus title tracks are 2 through 8 and 97 through 99.
-The longest track is 31, even though there are a lot that are movie-feature length.  I haven't bothered pinning down which one it is yet.
+** The feature move title track is number 39. **  The length is 1:20:05 and there are 17 chapters.  Audio for English, French and Spanish is Dolby Digital 5.1, 384 kbps.
 As you will see, there is a *lot* of data to sort through, which I'm guessing is intended to screw up or fool some DVD rippers.

 Here's the human-readable output of [[dvd_info]] which skips the invalid IFOs:
+** Edit: ** dvd_info now displays the track, but fills it with zeros (zero length, chapters, cells, audio streams, subpictures) so that it makes the output look more sane.

+==== HandBrake ====
+Here's the output of HandBrake 0.10-beta scanning track 31.  Interestingly enough, it reports the audio bitrate as 384 kbps ... not sure if that's another bomb planted in the DVD or not.
+** Edit: ** nope, DVDs can have up to 912 kbps for an MPEG2 stream.  I've just never seen one above 192 before. :)  See [[http://stnsoft.com/DVD/dvdmpeg.html|DVD - MPeg differences]]

+Also, HandBrake 0.10-rc2 segfaults on reading the DVD when using ''--scan --no-dvdnav'', because there are no cells on some of the tracks.  I've posted a bugfix [[https://forum.handbrake.fr/viewtopic.php?f=4&t=31093|here]].
