So, what was actually wrong with the discs that leaked back in February?
I just did a full comparison between the February version and the version I have now, and the audio tracks are bit for bit identical. The only difference is that the July versions include a 7.1 PCM track that was not available on the version from back in February. That's not surprising though, as that wasn't listed on the packaging for that version. Was it a menu problem?
The video tracks are different though. The July version has burnt-in subtitles for some of the Beatles' dialogue, and matches the streaming versions, whereas the February version has soft subtitles, and no subtitles on the video. So the video tracks are different.
