The Black Cauldron
The books are awesome. :)
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 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.
Accessing it with libdvdread 5.0.0, here's what you'll probably see:
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).
Here's the human-readable output of dvd_info which skips the invalid IFOs:
