@ DJ:
PowerDVD has a button for that in (on?) the main interface and even a hotkey (a)... so your solution appears to be way too complicated.

@ dionoea
I tried to write a bug report but the "register" button seems to be broken, too
i'll try again tomorrow

I just checked for that,
There is an option in the context menu under Navigation/DVD Menu/Angle
but when i click that it just jumps back to the main menu
