Why doesn’t it support menus?
Unofficial, third party media players that support blu-ray almost never can do menus. As is, I guess it’s hard enough to get them to work with AACS on encrypted discs, so it’s a bit of a hack job. And they need to keep up with changing keys, etc.
Hang on, are you saying that MPC HC can play BDs without a third party software to get rid of the encryption first?
