I know what was meant, if you read my response I said I was almost certain that I had set the settings in the player previously. I just checked. Disc Menu and Disc Audio are both set to English and Disc Subtitle is None. The TS1 disc starts, shows a language menu. Selecting English then causes the player to step through a number of titles (49, 54, etc.) it then sits on title 8/1 for a while, moves to title 15/1 then 16/1 and sits there some more. Black screen and no audio, all this time.
I have left it for some time, now it's moved onto 14/1, 14/2, waiting. Still all black.
Will leave it to run itself through while I switch back to TV for a while.
Edit: It eventually has made it to display MENU all by itself. The screen is black. However my Denon AVR reports 1080p/24 is the input from the player. Hmm. I give up for now, back to the real cheap no-name player for these discs.
