Haha!
I tested it on my own player when I received it, so I'd say it is confirmed (even the tracks can't be switched during the movie).
Thankfully given the film it's not too much of a big deal but I assume Italian subs popping up being being pretty distracting when you watch the whole thing.
I have the same problem with the French editions of COMMAND PERFORMANCE and ICARUS (which look better than the US discs), and I wish I'd knew how to rip them in order to make new copies of my own without any subs...
