some months ago i got a samsung smart tv,
the problem its when you use default subtitle (movie file + sub file) the subtitles are so small and almoust impossible to read, so i had to find another alternative to fix my problem, and i did find.

i use "AVIAddXSubs" to create a idx/sub file with my type of font, and size, and after i use "mkvmerge GUI" to mix in one file,
everything gets fine, without a little problem... the outline its gets a light grey colour instead of black, and on light scenes its real hard to read sinze it kind mix with the image...

anyone have any solution to turn the outline in black?
