The disc is getting decrypted, but there's an issue with this disc. The disc uses seamless branching and the very first file in the list uses different audio to the rest of the film so you can't make a 'movie only' by using a standard playlist. On my disc I had to determine the correct playlist, then look at the m2ts files used in that play list, then go into TSMuxer and load in all the files in order except the first one (it's only a logo so you don't miss anything). I then got TSMuxer to export it out as Blu-ray format which then worked
Hopefully that doesn't become the norm, because it seems like more effort than it's worth to me. The relevant pieces from the Handbrake log are:

Do you suppose that's symptomatic of what you're describing? And, based on what you're saying, it doesn't sound like this "problem" would be considered something to "fix" in AnyDVD, right?
