The problem is that I convert my bluray movies to apple tv 3, and ipad and iphone to stream them from itunes.
To convert the blurays I use the convert option on dvdfab 9.1.7.1 on yosemite, and the subtitles go to a diferent file, after adding the tags the movie plays well.
Then to have subtitles on apple tv and ipad, I add the subtitle files with iSubtitle, then save the file.
Using DVDFab media player, and sellecting the respective subtitle in the file, at que moment the subtilte tryes to appear, the player simply crashes.
Even with original iTunes decripted movies.
Using OSX 10.10 Yosemite, the problem occurs with M4V format, and MP4.
This bug is present for a long time now, it make DVDfab Media Player licenced, a inoperable player for me.
I hope they correct this bug soon, strange the programers dident notice this allready.
Thanks.
