That last comment, about DVD-A discs, hit a nerve with me. I don't know the client, but he's in the music industry and he just might bring some unusual kind of disc home from the studio... Do Sony and Oppo players play everything? (I'm not worried about discs from other regions.)
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
