Comment (by ltratt):

 Thanks for looking into this! There seems to be something even weirder
 going on than I first realised. mpv seems capable of playing at least the
 nut and mp4 files with proper synchronisation (to my eyes it drifts
 slightly with the mkv, but I might be seeing double at this point!). vlc,
 however, struggles with all of them (nut, mkv, mp4), drifting noticeably
 over time. So does youtube, for which the audio is heavily (unusably!) out
 of sync for the nut, mkv, and mp4 files. I have no idea if this has any
 bearing on this issue or not, but I thought it might be worth mentioning!
