-''ddrescue'' found some bad blocks while ripping it:
+** 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:

-Handbrake complains as well:
+==== 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]]
