Mkv Subtitles disappear...

Hi !

I'm going nuts with this issue... it only started a while ago...

I'm trying to play MKV files with an external Hebrew SRT Subtitles file and they simply won't show up...

sometimes on the first file I try they do show, but as soon as I go back to the library and try to play another file, the subtitles are
not showing up... (the menus won't even show me there are subtitles or give me the option to turn them back on)

Any help will be greatly appreciated !!!

More info...

I just tried the same setup on my Macbook Air, and it works fine...
I tried removing the serviio installation on the iMac (using the instructions on the serviio website) and reinstalled
but it is still not working...

Any Ideas would be great...

Thanks !

Could be corrupted susbtitle file, wrong profile, file name, etc.

I doubt it is the sort file, as i take the same file and mov to my Macbook Air, and it works fine there...

It happens with any file in any of my disks, not just a specific one...
It didn't happen in the past...

Any other specific fixes you can offer ?

Thanks !
