Quirky subtitles.

[jlj1950 7]

Hello,

 

I have three Japanese movies I converted from mp4 to mkv using  mkvtoolnix. I did so to internalize subtitles.
This time, and I've done this before, the movies would not play very well and the busy circle kept going round.
Occasionally, a few frames would run by but not enough to get Nerd Stats up. 
I thought direct play may have been activated for some reason.
Then I discovered something funny. I turned off subs in the movie presentation page, ran the movie,  which ran normally without the subs,
and added the subs from the player page. 
From then on, the movie would play normally wiith the subs on. 
I did this with all three and all three now play normally, using direct play.
Not sure there's a solution to this since the problem is not well defined and not, to my knowledge, reproducible.
I present the case for others reference and use.

I've added these files as an afterthought:

I suspect browser cache.  When you changed to a new version, your browser may have been unaware that a new video was there, if the filename of the video was exactly the same.  The browser might then start playing from a cached version of the video and run into trouble when it needed to pull new segments of the video as you played further along.  Just a guess.
