VLC doesn't find subtitles on network (SMB) shares.
- Name a movie and a subtitle file to the same name (except the extension), a.mkv and a.srt
- Upload them to a SMB-share
- Access this share from VLC and start playing a.mkv.
No subtitles are added.
- Move the two files from the SMB share to the ATV's internal storage
- Everything works as expected.
