In VLC theres also a setting to increase/decrease the subtitle delay. Theres a set of hotkeys to move it up/down by 50ms at a time, or you can go into the settings and enter a custom valur. Sometimes this doesnt work for a whole movie as the subtitles will just keep getting more and more out of sync, but if theyre just behind or ahead by a little bit consistently, then its a huge sanity saver.
