Asked them to check again. The mkv seems to have a 20s ident at the start that the subs are not prepared for. Even then I don't think it's quite in (looking at the scene around 1:55:47 where the guy pins a message to the dying man's chest, and the subs translate the message, I think...)

Anyway here we have some random files off the internet, they aren't in sync, and somehow it's ended up as DoM's fault.
