Hmmm... Guess it's not an issue with copy protection/AnyDVD. Using both Handbrake and MakeMKV (Been doing this for a LOOONNNGGG time, so not new to either), getting continual errors prior to encoding. Tried a lot of different ways of encoding. Some chatter elsewhere that its an issue with the HD audio on there, but couldn't even get it to work without audio. Not a single frame.
Downloaded CloneBD and its encoding seamlessly. Guess it's time to grab the credit card.
(Although I'd still like to figure out what's going on with this particular movie...)
