go to apple tv, and then click movies/music etc.
Schedule a call. Tell them the movie and the issue. I had purchased the movie and they gave me a refund. I told them I was not the only one having the issue and that their message boards had others with the same movie. They said, "we don't monitor the message boards".
So, give them a call and get a refund. the refunded me for my whole purchase. Then, I went on amazon and ordered the bluray WITH digital copy for 2 dollar less than I paid for just the digital copy. Suck it apple!
Bottom line, I trouble shooted it for them. They have a corrupt movie file that is missing subtitle tracts. I have experience creating playable blu-rays. I've also looked at how marvel movie discs are encoded. Usually, with subtitle tracks, you have a standard sub track which you can turn off or on. Then, there are sections of that same track called "forced subs". The forced display even with subs are off. This is generally used for foreign language scenes. HOWEVER, the marvel move discs typically do it different. They have a standard sub trac, THEN they have a separate foreign language only track that is ALWAYS forced, but is only encoded to show on certain scenes. It would appear that that track is entirely missing from the file apple has. Disney needs to fix it. But apple won't know to request the fix unless enough people request it. They told me they were escalating my ticket to the proper team to sort it. But I doubt it'll get much attention without more people calling.
Ugh.. apple genius' am i right? The guy I talked to on the phone didn't have ANY idea what I was talking about. *sigh* At least I got my refund.
