How to play a dvd movie with external subtitles? This is not about authoring the DVD (not similar to this question): just want to insert the DVD in a laptop, start it in a video player, and then add a separate subtitle that I have myself found. (Some DVD movies contain no subtitles - or some subtitles may be needed that are not on the DVD.)

I know how to do that in Windows and in Linux - without VLC: it can try but has bad results in this respect. - Every time I try it, external subtitle display for a DVD in VLC is erratic; usually subtitles are not always displayed, or they disappear after a while, namely after pause/play or after going back and forth. (See here, here, here, here about this old bug that is not yet completely gone, afaict.) Here it says VLC is the only Mac player that can do the job. But is it?

Are there some Mac video players that could achieve this task - like MPC-HC (Potplayer, etc) can in Windows (and MPV and SMPlayer in Linux)?
This is a temporary answer as I don't have a Mac at hand now. 

I have to test on a Mac, but the Windows version of 5kPlayer can do it very well; and it has a Mac version.

Also, KMPlayer can also do it (also tested just in Windows for the moment) and it has a Mac version it seems (here - Mac Alpha Version: have yet to test too).
