Subtitles on UNC cannot be found

Workaround is to map to a drive letter.

"Conversion failed. The transcoder failed to start up." message when trying to play videos with external subtitles

Until someone comes in with a better tip or a full solution, I decided to use the boring workaround of mapping my NAS to Z:. After a change of all library paths and full metadata updates, it works.
