Problem to play .mkv files on Panasonic DMP-BDT500

[justpassthrough]

I have 2 renders : Panasonic DMP-BDT500 and Panasonic Viera ST60,
Above 2 renders in UMS V.4.3.1 was working perfectly to paly .mkv files.

But after I update the UMS software to the newer version (include V.5.2.1), 2 renders always occur the same error in some .mkv file.
Error Message "ffmpeg.exe has a return code of 1! Maybe an error occurred..." displayed in the log then process stopped.

Following list the problem file media info and debug log attchment for you reference,

The problem is in external subtitles file which the ffmpeg is unable to parse. They may be corrupted or so. Can you send this subtitles here to check what is wrong?

Here is the subtitle of Interstellar.2014.cht.srt in attahcment for you check ,
and I am curious why it just occur the error in the newer version UMS (like V. 5.2.1) ,but play successful in V.4.3.1.

Thanks for the info. The subs file looks good. Can you try to go back to the UMS V.4.3.1 play the same file and send the log? I would like to realize if the problem is the FFmpeg version or there is something bad in our code. Thanks.
