HDMV vs BDJ
I have read that a BluRay disc could be either HDMV or BDJ. But here in the forum, I see people talking about mixed discs.
What is the truth? Can you start the menus in HDMV and launch a BDJ application, and then return to HDMV when the application is over? Or do you need to program everything in BDJ?
Sorry for this stupid question, but I am beginning!
