| ** 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. | ** The Black Cauldron ** on DVD has some new copy protection on it (I think).

| 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.

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 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]]. | ||
