Disney DVDs Chapters Rip in Wrong Order (Score 1)

Many Disney DVDs attempt to fool DVD rippers by having a fake chapter file that puts the chapters out of order. For these discs, you need to find and load the correct chapter file.

I've had this problem with Bolt and with Wall-E, though I can't speak specifically to Howl's Moving Castle.

So, this problem, at least, may not be the fault of your Linux rippers.
