I have a suggestion for your player.
I just watched the GOT series and wanted to be able to read the foreign languages with the subtitles and found that there is a really lot of English subtitles (25-30) for each episode, but most of them are not good.
- Not sync'd correctly
- Only shows the English dialog and says something like (Speaking Valarian) when a foreign language is spoken
- Wrong Episode
- Etc...
It takes a really long time to go through all the subtitle files to find one that works correctly, and for something like GOT which has like 75 episodes, it adds up to quite a bit of time.
Now, I invested that time to find the right subtitle to use, but none of your other viewers can benefit from the considerable time I spent. If you added up/down voting to the subtitle file, I would have gladly voted up the ones that worked properly and voted down the ones that didn't.
Not sure if it's technically possible for you to implement something like this, but if you could, I think your viewers would appreciate it.
Also - some foreign movies don't have any correct English subtitles at all, so I download them from the internet, and upload them to the player. It sometimes takes a couple of tries before I find one that's correct, but they work well once I do. However, the correct subtitle does not get permanently added to the list for the next viewer to use. If you come up with a way to submit new, better, subtitles to foreign movies, I'd be glad to do it (mostly Korean, Japanese, and Chinese).
