+** The Black Cauldron ** on DVD has some new copy protection on it (I think).  Either way, it's a pain, and had to work around some stuff.  Thankfully, it flushed out some bugs in [[dvd_info]] that are now fixed!  The basic takeaway is this: never assume that an IFO is valid.
+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 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 some of the stats:
+  * 197 audio tracks
+  * 293 subtitles
+  * 956 chapters
+  * 1,262 cells
+Accessing it with libdvdread 5.0.0, here's what you'll probably see:
+<code>
+libdvdread: Invalid IFO for title 2 (VTS_02_0.BUP).
+libdvdread: Invalid IFO for title 3 (VTS_03_0.BUP).
+libdvdread: Invalid IFO for title 4 (VTS_04_0.BUP).
+libdvdread: Invalid IFO for title 5 (VTS_05_0.BUP).
+libdvdread: Invalid IFO for title 6 (VTS_06_0.BUP).
+libdvdread: Invalid IFO for title 7 (VTS_07_0.BUP).
+libdvdread: Invalid IFO for title 8 (VTS_08_0.BUP).
+libdvdread: Invalid IFO for title 36 (VTS_36_0.BUP).
+libdvdread: Invalid IFO for title 37 (VTS_37_0.BUP).
+libdvdread: Invalid IFO for title 38 (VTS_38_0.BUP).

+==== dvd_info ====
+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.
