Also confirming that the sync issue happens on hardware. But also, I selected the Spanish audio track from the 1981 menu and it just played the English track 1. I will double check and see if I can repeat the error tomorrow.
I saw similar behavior when playing it on Kodi, but i sometimes get weird issues like that so i wasn’t sure. On Kodi i would have to restart the movie, and then i could select spanish and it would play spanish subtitles. so it seems to just be that it doesn’t switch between subtitles once you already have one subtitle enabled? (haven’t gone back to retest though)
The only other menu thing that stuck out to me was that the 1977 button text showed up before the full menu was visible for the 1997 1981 crawl choices. it might be just because of menu lead in time or something and maybe not really an issue, but the fact that i didn’t seen the 1981 text seemed funny to me (sorry i haven’t retested this, and am relying on my memory)
