I noticed my existing subtitle configuration that's worked well with Mezzmo and my STB's isn't working through the browser. My subtitles have all been embedded into MKV's so that my STB's all display them without issue. This isn't working when streaming through the browser with the same videos. I tried to move the .srt files to the same folder as the movie and made sure that both files are named the same but this still doesn't allow the subs to display through the browser. The only configuration I found that works is to manually select the subtitle through each video's subtitle setting. Once that's done, the subs are displayed through the browser without issue.

Is this the only way to get the subs to display through the browser or have I missed a step somewhere?
