The only PUOps I run are:
Menu Domain - 196 (title play, next pgn, prev pgn)
Titles domain - 4 (title play)
The reason I inhibit title play is that many DVDs are not authored properly - especially ones with advanced protection - and require certain registers to be set on entry. So, I prefer to get to a title via a menu.
I inhibit next/prev pgn in the menus for multi-celled menus. I prefer to navigate menus via buttons (that’s what they were designed for) and not via the next / prev button on the remote - again, the idea is correct navigation always.
