One of you please attach the dvdfab_internal log session from Spectre. Also, what are the time marks where the translation subs first appear?
Never mind, I found them. They are in the bottom English stream. If using Ripper, you should select this stream only, then it will not matter if you select Display Only Forced or not, although they do appear to be forced. (This is from the Region A (US) Blu-ray).
