Bug#1032972: handbrake: debian version of handbrake does NOT handle subtitles correctly

[js jb]

I've installed the snapshot version of handbrake from handbrake.fr directly 
(via flatpak)and verified that on the same DVDs, it generates the subtitles 
perfectly.
I also built the debian version of handbrake from source and that one still has 
the same problems.One can also see the subtitles overlaying each other so that 
in rapid dialog multiple subtitles appearone on top of each other, making them 
all illegible.  This does not happen in the handbrake snaphshot.
thanks,--jack
